In their simplest form they consist of a wire through which passes the current to be measured, some arrangement being provided for measuring the small expansion produced by the heat generated in the wire.

The reason is that the heat produced in a given time in a wire is proportional to the square of the strength of the current passing through it, and hence the rate at which the heat is produced in the wire, and therefore its temperature, increases much faster than the current itself increases.

When a current is passed through the wire, continuous or alternating, it creates heat, which expands the air in the bulb and forces the liquid up one side of the U-tube to a certain position in which the rate of loss of heat by the air is equal to the rate at which it is gaining heat.

As this vast mass cooled it must by the laws of heat have contracted towards the centre, and as it contracted it must, according to a law of dynamics, rotate more rapidly.

The daily outpour of heat from the sun at the present time suggests a profound argument in support of the nebular theory.

The amount of the sun's heat has been estimated, but we receive on the earth less than one two-thousand-millionth part of the whole radiation.

Now what supplies this heat?

We might at first suppose that the sun was really an intensely heated body radiating out its heat as does white-hot iron, but this explanation cannot be admitted, for there is no historical evidence that the sun is growing colder.

We have not the slightest reason to think that the radiation from the sun is measurably weaker now than it was a couple of thousand years ago, yet it can be shown that, if the sun were merely radiating heat as simply a hot body, then it would cool some degrees every year, and must have cooled many thousands of degrees within the time covered by historical records.

We, therefore, conclude that the sun has some other source of heat than that due simply to incandescence.

It might, for example, be suggested that the heat of the sun was supplied by chemical combination analogous to combustion.

We cannot, therefore, admit that the source of the heat in the sun is to be found in any chemical combination taking place in its mass.

Where then can we find an adequate supply of heat?

It can be shown that unless a quantity of meteors in collective mass equal to our moon were to plunge into the sun every year the supply of heat could not be sustained from this source.

As the sun loses heat it contracts, and every pair of particles in the sun are nearer to each other after the contraction than they were before.

The energy due to their separation is thus less in the contracted state than in the original state, and as that energy cannot be lost it must reappear in heat.

The sun is thus slowly contracting; but as it contracts it gains heat by the operation of the law just referred to, and thus the further cooling and further contraction of the sun is protracted until the additional heat obtained is radiated away.

In this way we can reconcile the fact that the sun is certainly losing heat with the fact that the change in temperature has not been large enough to be perceived within historic times.

That vigorous chemical action is accompanied by a brisk evolution of heat is evident from such familiar examples as the combustion of fuel or the explosion of gunpowder.

Hess, from his work, arrived at the converse conclusion, that when a series of bases were used to neutralize a given amount of an acid, the heat of neutralization was always the same.

Andrews likewise found that when the heat evolved on.

This affords an example of a principle which had been stated by Hess in a very general form under the name of the Law of Constant Heat Sums - namely, that the thermal effect of a given chemical action is the same, independently of the character and number of the stages in which it takes place.

Hess now observed that in the process of mixing such neutral solutions no thermal effect was produced - that is, neutral salts in aqueous solution could apparently interchange their radicals without evolution or absorption of heat.

Silbermann, whose chief theoretical achievement was the recognition that the heat of neutralization of acids and bases was additively composed of two constants, one determined by the acid and the other by the base.

The existence of reactions which are reversible on slight alteration of conditions at once invalidates the principle, for if the action proceeding in one direction evolves heat, it must absorb heat when proceeding in the reverse direction.

When the first system then is transformed into the second, the excess of energy which the former possesses must appear in the shape of heat, light, electrical energy, mechanical energy, &c. It is for the most part a simple matter to obtain the excess of energy entirely in the form of heat, the amount of which is easily susceptible of measurement, and thus the existence of thermochemistry as a practical science is rendered possible.

The total thermal effect, too, which is associated with the transformation, must be the same, whether the transformation is conducted directly or indirectly (Hess's Law of Constant Heat Sums), since the thermal effect depends only on the intrinsic energies of the initial and final systems.

For example, when metallic zinc is dissolved in dilute sulphuric acid with production of zinc sulphate (in solution) and hydrogen gas, a definite quantity of heat is produced for a given amount of zinc dissolved, provided that the excess of energy in the initial system appears entirely as heat.

It is of course in such a case necessary to know the specific heat of the liquid in the calorimeter.

The same type of calorimeter is used in determining the heat of solution of a solid or liquid in water.

Combustion calorimeters are employed for observing the heat generated by the brisk interaction of substances, one of which at least is gaseous.

If now it is required to find the heat of formation of the compound CO, which cannot be directly ascertained, we have merely to subtract the second equation from the first, each symbol representing constant intrinsic energy, and thus we obtain C+0 - 00= 26300 cal., or C+0=C0+26300 cal., that is, the heat of formation of a gramme-molecule of carbon monoxide is 26300 cal.

This assumption has the great advantage, that the intrinsic energy of a compound relatively to its elements now appears as the heat of formation of the compound with its sign reversed.

With knowledge then of the heats of formation of the substances involved in any chemical action, we can at once calculate the thermal effect of the action, by placing for each compound in the energy-equation its heat of formation with the sign reversed, i.e.

Some of these pass into their elements with explosive violence, owing to the heat generated by their decomposition and the gaseous nature of the products.

The relation between the heat of combustion of a hydrocarbon and its heat of formation may be readily seen from the following example.

The above equation may consequently be written, if x is the heat of formation of methane, -x+0 = -94300-(2 X 68300) +213800 x =17000 cal.

The oxygen contained in the compound was deducted, together with the equivalent amount of hydrogen, and the heat of combustion of the compound was then taken to be equal to the heats of combustion of the elements in the residue.

The observed heat of combustion of sugar is, however, 1354000, so that the error of the rule is here 20 per cent.

A much better approximation to the heat of combustion of such substances is obtained by deducting the oxygen together with the amount of carbon necessary to form C02, and then ascertaining the amount of heat produced by the residual carbon and hydrogen.

In addition to this, the further regularity has been observed that when the powerful monobasic acids are neutralized by the powerful monacid bases, the heat of neutralization is in all cases the same.

It was at one time thought that the greater the heat of neutralization of an acid with a given base, the greater was the strength of the acid.

When substances readily combine with water to form hydrates, the heat of solution in water is usually positive; when, on the other hand, they do not readily form hydrates, or when they are already hydrated, the heat of solution is usually negative.

The dry season lasts from October to May, the hottest months appear to be in March and April, when the heat is increased by the burning of the corn and henequen fields.

These aguadQS were huge basins, paved and cemented, with underground cisterns, also lined with stone and cement, which may have been used for the protection of water against heat when the principal supply had become exhausted.

The climate is generally such as to secure the population the necessaries of life without severe labour; the extremes of heat and drought are such as to render the land unsuitable for pasture, and the people everywhere subsist by cultivation of the soil or commerce, and live in settled villages or towns.

The climate is very severe, with great extremes of heat and cold.

The summers are hot, though short in the northern latitudes, the maximum of summer heat being comparatively little less than that observed in the tropical countries farther south.

In the summer a great accumulation of solar heat takes place on the dry surface soil, from which it cannot be released upwards by evaporation, as might be the case were the soil moist or covered with vegetation, nor can it be readily conveyed away downwards as happens on the ocean.

In the winter similar consequences ensue, in a negative direction, from the prolonged loss of heat by radiation in the long and clear nights - an effect which is intensified wherever the surface is covered with snow, or the air little charged with vapour.

In illustration of the very slow diffusion of heat in the solid crust of the earth, and as affording a further indication of the climate of northern Asia, reference may here be made to the frozen soil of Siberia, in the vicinity of Yakutsk.

The very high summer temperatures of the area north of the tropic of Cancer are sufficiently accounted for, when compared with those observed south of the tropic, by the increased length of the day in the higher latitude, which more than compensates for the loss of heat due to the smaller mid-day altitude of the sun.

These tend very greatly to arrest the increase of the summer heat over the area where they prevail, and otherwise give it altogether peculiar characteristics.

The great summer heat, by expanding the air upwards, disturbs the level of the planes of equal pressure, and causes an outflow of the upper strata from the heated area.

This diminution of pressure, which continues as the heat increases till it reaches its maximum in July soon after the solstice, is followed by the corresponding development of the south-west monsoon; and as the barometric pressure is gradually restored, and becomes equalized within the tropics soon after the equinox in October, with the general fall of temperature north of the equator, the south-west winds fall off, and are succeeded by a north-east monsoon, which is developed during the winter months by the relatively greater atmospheric pressure which then occurs over Asia, as compared with the equatorial region.

In both cases, however, the storms appear to advance towards the area of greatest heat.

Such a reduction of temperature is brought about along the greater part of the coasts of India and of the BurmoSiamese peninsula by the interruption of the wind current by continuous ranges of mountains, which force the mass of air to rise over them, whereby the air being rarefied, its specific capacity for heat is increased and its temperature falls, with a corresponding condensation of the vapour originally held in suspension.

The area between the southern border of Siberia and the margin of the temperate alpine zone of the Himalaya and north China, comprising what are commonly called central Asia, Turkestan, Mongolia and western Manchuria, is an almost rainless region, having winters of extreme severity and summers of intense heat.

As early as 1804, Humboldt expressed the opinion that petroleum was produced by distillation from deep-seated strata, and Karl Reichenbach in 1834, suggested that it was derived from the action of heat on the turpentine of pine-trees, whilst Brunet, in 1838, adumbrated a similar theory of origin on the ground of certain laboratory experiments.

Petroleum has very long been known as a source of light and heat, while the use of crude oil for the treatment of wounds and cutaneous affections, and as a lubricant, was even more general and led to the raw material being an article of commerce at a still earlier date.

An alternating current of one ampere is defined to be one which produces the same heat in a second in a wire as the unit continuous current defined as above to be one ampere.

The soap is melted by heat, the glycerin is stirred in, and the mixture strained and poured into forms, in which it hardens but slowly into a transparent mass.

In the more complex gases the specific heat varies considerably with temperature; only in the case of monatomic gases does it remain constant.

This states that " the atomic heat (the product of the atomic weight and specific heat) of all elements is a constant quantity."

He regarded these anomalies as solely due to the chemical nature of the elements, and ignored or regarded as insignificant such factors as the state of aggregation and change of specific heat with temperature.

Since the atomic heat of the same element varies with its state of aggregation, it must be concluded that some factor taking this into account must be introduced; moreover, the variation of specific heat with temperature introduces another factor.

We now proceed to discuss molecular heats of compounds, that is, the product of the molecular weight into the specific heat.

Neumann, who, in 1831, deduced from observations on many carbonates (calcium, magnesium, ferrous, zinc, barium and lead) that stoichiometric quantities (equimolecular weights) of compounds possess the same heat capacity.

Regnault confirmed Neumann's observations, and showed that the molecular heat depended on the number of atoms present, equiatomic compounds having the same molecular heat.

Kopp systematized the earlier observations, and, having made many others, he was able to show that the molecular heat was an additive property, i.e.

The specific heat of a compound may, in general, be calculated from the specific heats of its constituent elements.

Conversely, if the specific heats of a compound and its constituent elements, except one, be known, then the unknown atomic heat is readily deducible.

Similarly, by taking the difference of the molecular heats of compounds differing by one constituent, the molecular (or atomic) heat of this constituent is directly obtained.

The specific heat of indium is o 057; and the atomic heats corresponding to the atomic weights 38, 76 and 114 are 3.2, 4.3, 6.5.

As a general rule, compounds formed tive with a great evolution of heat have high boiling-points, and vice versa.

Specific Heat and Composition.-The nature and experimental determination of specific heats are discussed in the article Calorimetry; here will be discussed the relations existing between the heat capacities of elements and compounds.

In the article Thermodynamics it is shown that the amount of heat required to raise a given weight of a gas through a certain range of temperature is different according as the gas is maintained at constant pressure, the volume in creasing, or at constant volume, the pressure increasing.

This is the general equation for calculating the heat of combustion of a hydrocarbon.

In consequence of the elevation of the plateau and the dryness of the air, the heat is less oppressive than is indicated by the temperatures recorded.

A pupil of Nessus, or, as some accounts prefer, of Democritus himself, he was a complete sceptic. He accepted the Democritean theory of atoms and void and the plurality of worlds, but held a theory of his own that the stars are formed from day to day by the moisture in the air under the heat of the sun.

The muscle-albumins include " myosin " or paramyosinogen, a globulin, which by coagulation induces rigor mortis, and the closely related " myosinogen " or myogen; myoglobulin and myoalbumin are also found in muscles.

The primary products of the dissociation of albumins are the albumoses, characterized by not being coagulable by heat, more soluble than the albumins, having a far less complex composition, and capable of being " salted (7) out " by certain salts, and the peptones, similar to albumoses but not capable of being " salted out "; moreover, peptones are less complex than albumoses.

The heat liberated, then, is almost exclusively that produced by the formation of water from its ions.

An exactly similar process occurs when any strongly dissociated acid acts on any strongly dissociated base, so that in all such cases the heat evolution should be approximately the same.

This is fully borne out by the experiments of Julius Thomsen, who found that the heat of neutralization of one gramme-molecule of a strong base by an equivalent quantity of a strong acid was nearly constant, and equal to 13,700 or 13,800 calories.

We can calculate the heat of formation from its ions for any substance dissolved in a given liquid, from a knowledge of the temperature coefficient of ionization, by means of an application of the well-known thermodynamical process, which also gives the latent heat of evaporation of a liquid when the temperature coefficient of its vapour pressure is known.

If the chemical changes which occur in the cell were allowed to take place in a closed vessel without the performance of electrical or other work, the change in energy would be measured by the heat evolved.

Since the final state of the system would be the same as in the actual processes of the cell, the same amount of heat must give a measure of the change in internal energy when the cell is in action.

Thus, if L denote the heat corresponding with the chemical changes associated with unit electric transfer, Le will be the heat corresponding with an electric transfer e, and will also be equal to the change in internal energy of the cell.

Similarly, the heat which accompanies the dissolution of one electrochemical unit of copper is 3.00 calories.

The efficacy of heat or of an acid, an alkali or other agent in promoting coagulation depends on the character of the latex, and varies with that obtained from different plants.

Another disadvantage of uncovered soil in a plantation of young rubber trees is that the ground under the heat of a tropical sun rapidly loses its moisture.

Caoutchouc is a bad conductor of heat and electricity, and alone or mixed with other materials is employed as an electrical insulator.

Before commencing the mastication it is generally necessary to warm the apparatus by means of steam; but as the operation proceeds the heat produced requires to be moderated by streams of cold water flowing through channels provided for the purpose.

To convert the masticated rubber into rectangular blocks, it is first softened by heat, and then forced into iron boxes or moulds.

Vulcanization is then effected by steam heat, and, the preparation on the cloth being softened by water, the sheet of rubber is readily removed.

When the vulcanization of rubber is carried too far, from the presence of a very large proportion of sulphur and an unduly long action of heat, the caoutchouc becomes hard, horn-like, and often black.

The micas are bad conductors of heat and electricity, and it is on these properties that many of their technical applications depend.

Being a bad conductor of heat it is used for the packing and jackets of boilers and steam-pipes.

Its foreshore consists of a great expanse of firm, bright sands, and the mildness of its winter climate is attributed to the radiation of heat from them.

Among other subjects at which he subsequently worked were the absorption of gases in blood (1837-1845), the expansion of gases by heat (1841-1844), the vapour pressures of water and various solutions (1844-1854), thermo-electricity (1851), electrolysis (1856), induction of currents (1858-1861), conduction of heat in gases (1860), and polarization of heat (1866-1868).

The heat is then raised in (relative) absence of air, when the two elements named unite into sulphur-dioxide, while a regulus of molten lead remains.

At this stage as a rule some rich slags of a former operation are added and a quantity of quicklime is incorporated, the chief object of which is to diminish the fluidity of the mass in the next stage, which consists in this, that, with closed air-holes, the heat is raised so as to cause the oxide and sulphate on the one hand and the sulphide on the other to reduce each other to metal.

Charcoal is now added, and the heat urged on to obtain Pressblei, an inferior metal formed partly by the action of the charcoal on the oxide of lead.

To remove tin, arsenic and antimony, the lead has to be brought up to a bright-red heat, when the air has a strongly oxidizing effect.

If the lead is to be liquated and then brought to a bright-red heat, both operations are carried on in the same reverberatory furnace.

After it has been melted down and brought to a red heat, the blast, admitted at the back, oxidizes the lead and drives the litharge formed towards the front, where it is run off.

In the reverberatory furnace, similar to the one used in softening, the lead is brought to a brightred heat and air allowed to have free access.

The conductivity for heat (Wiedemann and Franz) or electricity is 8.5, that of silver being taken as loo.

The specific heat is.

It is decomposed by heat into oxide, nitrogen peroxide and oxygen; and is used for the manufacture of fusees and other deflagrating compounds, and also for preparing mordants in the dyeing and calico-printing industries.

The heat of summer is most oppressive.

Plutarch (Cicero, 5) mentions it as reported of Aesopus, that, while representing Atreus deliberating how he should revenge himself on Thyestes, the actor forgot himself so far in the heat of action that with his truncheon he struck and killed one of the servants crossing the stage.

In order to attain this result it was formerly the practice to raise the metal to a bright red heat, and allow it to cool while carefully guarded from magnetic influence.

Fleming, it 47r requires about 18 foot-pounds of work to make a complete mag netic cycle in a cubic foot of wrought iron, strongly magnetized first one way and then the other, the work so expended taking the form of heat in the mass.

But when exceptionally strong fields are desired, the use of a coil is limited by the heating effect of the magnetizing current, the quantity of heat generated per unit of time in a coil of given dimensions increasing as the square of the magnetic field produced in its interior.

Abrupt alterations, take place in its density, specific heat, thermo-electric quality, electrical conductivity, temperature-coefficient of electrical resistance, and in some at least of its mechanical properties.

It is remarkable that if a flow of heat be substituted for a current of electricity a closely allied group of " thermo-magnetic effects " is presented.

Its touched eased the heat and pain.

When it'd finished, she felt little pain, and the heat was completely gone.

He certainly felt human with a massive male body expending heat and warmth.

The pinch was less today, and the pain gone instantly, replaced by heat and warmth.

His thumb traced the line of her jaw lightly, and heat skittered through her.

She felt the heat --his heat --within her, branding her from the inside out.

Katie supplied with no heat.

She surrendered to the heat in her blood.

If she stepped just an inch closer, she.d feel his body heat.

He turned her to face him, and she gazed up at him, once again awed by his size, heat, and intensity.

Her blood was already on fire from their bodies being pressed together, and heat pooled in the base of her belly.

He was trying not to let the feel of Katie.s skin heat his blood, but her nearness and direct gaze lit him afire.

Even at the safe distance, his body heat made her uncomfortably warm.

An unexpected heat jarred her to her core, and the earth beneath her feet shook violently enough to rattle her teeth.

The heat of his large hands made her feel as if she wore no clothing.

Heat flared within her body, and her imagination painted an image of the warrior before her without the clothing.

His incredible strength, heat, and scent calmed her fear as much as they excited the woman within her.

She could feel his body heat and felt pinned beneath the intensity of his gaze.

The landscape was open and flat, the heat making the ground shimmer.

She rose to see how far away they were from the horizon, miserable in the heat.

Night brought a chill as uncomfortable as the heat of the day.

The dwelling was warm already in the midmorning, and she wondered how she'd survive another day of heat like yesterday's.

Her senses filled with his taste, scent, the heat of his body, enveloping her yet never enough.

His large frame radiated heat.

The heat has been lowered now that the men have left and it is oh so cold as I lay huddled here beneath my thin blankets.

You mean you'd start blasting away on the spur of the moment— in the heat of passion.

Fully alert, he listened, but heard only night noises, the ticking of the hall clock, a slight breeze, the ever-present furnace rumbling heat to the old building.

She turned and in one motion straddled him, pinning his arms above his head, the heat of her body pressed against him.

With the first sip, heat invaded the newborns' throats and bellies.

The first was to maintain enough control to avoid crushing them in the heat of passion.

He decided that even if she sounded like a cat in heat, he would gush over her with praise.

I can heat some up for you.

The house looked so far away as it shimmered in heat waves.

Heat rolled over him as he was flung towards the weed-infested parking lot.

Heat pulsed off the building in waves, aided by a soft, cold breeze.

Heat then red light washed over them.

The body heat of someone kneeling beside her made her blink, and she braced herself for the doc shooting her up again.

She felt his body heat and stared at his wide chest.

Her breathing was hard, his body heat piercing her clothes.

Her face flamed with heat, and she strained against him.

She touched him timidly, her cool hands branding him as heat coursed through him.

Overwhelmed, she closed her eyes, enjoying the heat.

Heat ripped through the cabin of the helicopter, bringing with it the scent of scorched metal.

At least now they'll have real heat, she thought to herself.

Heat surged through his body, but he hesitated.

Deidre shifted with a grunt.  Katie sat back on her haunches, not sure what to do when she couldn't see what she was trying to cut.  Deidre was shaking as hard as Katie was, and Katie crept closer for body heat.

And then they got sick of sitting around, and maybe ran out of dough I guess and figured the heat was off, so they came out.

What's the heat if I double rent once in awhile?

The heat wouldn't let up.

That's a lot of heat for a lousy two or three million.

There was another concern—once the bikers hit the lower ele­vation and the heat of the afternoon, they would be shedding outer gear and perhaps identifying numbers with them.

It wouldn't take more than a few minutes in this heat before she would be ready to jump back into the water.

Below, the pond glistened in the evening heat, as if winking up at her.

You can get in out of the heat and you don't have to walk so far to do the chores.

Heat rushed up her neck.

The idea brought heat to her face.
