An electrified conductor is a store of energy, and from the definition of potential it is clear that the work done in increasing the charge q of a conductor whose potential is v by a small amount dq, is vdq, and since this added charge increases in turn the potential, it is easy to prove that the work done in charging a conductor with Q units to a potential V units is z QV units of work.

Accordingly the number of electric cells into which the space round is cut up is equal to twice the energy stored up, or each cell contains half a unit of energy.

This harmonizes with the fact that the real seat of the energy 3f electrification is the dielectric or insulator surrounding the charged conductor.'

But this simple relation is only true of the net balances of heat and work in a complete cyclical process, which must be adopted for theoretical purposes if we wish to eliminate the unknown changes of intrinsic energy.

The significance of relation (I) is best appreciated by considering the graphic representation of quantities of heat and energy on a work-diagram.

Any closed path or figure, such as ABCD, represents a complete cycle or series of operations, in the course of which the substance is restored to its original state with respect to temperature, intrinsic energy and other properties.

If the substance in any state such as B were allowed to expand adiabatically (dH = o) down to the absolute zero, at which point it contains no heat and exerts no pressure, the whole of its available heat energy might theoretically be recovered in the form of external work, represented on the diagram by the whole area BAZcb under the adiabatic through the state-point B, bounded by the isometric Bb and the zero isopiestic bV.

The change of the intrinsic energy in passing from one state to another, as from B to C is represented by the addition of the heat-area H= Bczz', and the subtraction of the work-area W = BCcb.

It follows from the first law that the intrinsic energy of a substance in a given state must always be the same, or that the change of E in any transformation must depend only on the initial and final states, and not on the path or process.

Since the change of energy is independent of the path, the finite change between any two given states may be found by integration along any convenient path.

The change of energy at constant volume is simply sdo, the change at constant temperature is (odp/de - p)dv, which may be written dE/de (v const) =s, dE/dv (0 const) =odp/do - p .

Observing that F is a function of the co-ordinates expressing the state of the substance, we obtain for the variation of S with pressure at constant temperature, dS/dp (0 const) '=' 2 F/dedp =-0d 2 v/d0 2 (p const) (12) If the heat supplied to a substance which is expanding reversibly and doing external work, pdv, is equal to the external work done, the intrinsic energy, E, remains constant.

The lines of constant energy on the diagram are called Isenergics.

The energy E and the total heat F are functions of the temperature only, by equations (9) and (I I), and their variations take the form dE = sdO, d F = Sd0.

Under this condition the increase of intrinsic energy would be equal to the heat absorbed, and would be indicated by fall of temperature of the calorimeter.

Joule failed to observe any change of temperature in his apparatus, and was therefore justified in assuming that the increase of intrinsic energy of a gas in isothermal expansion was very small, and that the absorption of heat observed in a similar experiment in which the gas was allowed to do external work by expanding against the atmospheric pressure was equivalent to the external work done.

If we consider any short length of the stream bounded by two imaginary cross-sections A and B on either side of the plug, unit mass of the fluid in passing A has work, p'v', done on it by the fluid behind and carries its energy, E'+ U', with it into the space AB, where U' is the kinetic energy of flow.

In passing B it does work, p"v", on the fluid in front, and carries its energy, E"+ U", with it out of the space AB.

If there is no external loss or gain of heat through the walls of the pipe, and if the flow is steady, so that energy is not accumulating in the space AB, we must evidently have the condition E'+U'+p'v' =E'+ U"+p"v" at any two cross-sections of the stream.

The expression for the change of intrinsic energy E between any given limits poOo to po is readily found by substituting these values of the specific heats in equations (II) or (13), and integrating between the given limits.

The energy is less than that of an ideal gas by the term npc. If we imagine that the defect of volume c is due to the formation of molecular aggregates consisting of two or more single molecules, and if the kinetic energy of translation of any one of these aggregates is equal to that of one of the single molecules, it is clear that some energy must be lost in co-aggregating, but that the proportion lost will be different for different types of molecules and also for different types of co-aggregation.

If two monatomic molecules, having energy of translation only, equivalent to 3 degrees of freedom, combined to form a diatomic molecule with 5 degrees of freedom, the energy lost would.

If two diatomic molecules, having each 5 degrees of freedom, combine to form a molecule with 6 degrees of freedom, we should have n = 2, or the energy lost would be 2pc per unit mass.

The loss of energy could not be greater than this on the simple kinetic theory, unless there were some evolution of latent heat of co-aggregation, due to the work done by the mutual attractions of the co-aggregating molecules.

If mechanical work or kinetic energy is directly converted into heat by friction, reversal of the motion does not restore the energy so converted.

In all such cases there is necessarily, by Carnot's principle, a loss of efficiency or available energy, accompanied by an increase of entropy, which serves as a convenient measure or criterion of the loss.

In this case the work of expansion, pdv, is expended in the first instance in producing kinetic energy of motion of parts of the gas.

Assuming that no heat is supplied from external sources and no external work is done, the intrinsic energy remains constant by the first law.

The final state of the substance, when equilibrium has been restored, may be deduced from this condition, if the energy can be expressed in terms of the co-ordinates.

But the line of constant energy on - the diagram does not represent the path of the transformation, unless it be supposed to be effected in a series of infinitesimal steps between each of which the substance is restored to an equilibrium state.

If dW is the external work done, dH the heat absorbed from external sources, and dE the increase of intrinsic energy, we have in all cases by the first law, dH-dE=dW.

The intrinsic energy, E, is similarly represented by the area DZ'Vd under the adiabatic to the right of the isometric Dd.

The increment of this area (or the decrement of the negative area E--04) at constant temperature represents the external work obtainable from the substance in isothermal expansion, in the same way that the decrement of the intrinsic energy represents the work done in adiabatic expansion.

The function J = E-94,, has been called the " free energy " of the substance by Helmholtz, and 90 the " bound energy."

These functions do not, however, represent energy existing in the substance, like the intrinsic energy; but the increment of 90 represents heat supplied to, and the decrement of (E-04) represents work obtainable from, the substance when the temperature is kept constant.

This function is also called the " thermodynamic potential at constant volume " from the analogy with the condition of minimum potential energy as the criterion of stable equilibrium in statics.

Motion is obtained from a continuous-current generator driven by an alternating motor with a very heavy fly-wheel, a combination known as the Ilgner transformer, which runs continuously with a constant draught on the generating station, the extremely variable demand of the winding engine during the acceleration period being met by the energy stored in the fly-wheel, which runs at a very high speed.

Thus the molecular theory of matter, as we have now pictured it, leads us to identify heat-energy in a body with the energy of motion of the molecules of the body relatively to one another.

The molecules of the two surface-layers will exert forces upon one another, so that, when the rubbing takes place, each layer will set the molecules of the other into motion, and the energy of rubbing will be used in establishing this heat-motion.

As the temperature of a body increases the average energy of the molecules will increase, and therefore the range of their excursions from their positions of equilibrium will increase also.

The substance attains to a perfectly liquid state as soon as the energy of motion of the molecules is such that there is a constant rearrangement of position among them.

Moreover, the molecules which escape are, on the whole, those with the greatest energy.

The average energy of the molecules of the liquid is accordingly lowered by evaporation.

If the system is supposed to obey the conservation of energy and to move solely under its own internal forces, the changes in the co-ordinates and momenta can be found from the Hamiltonian equations aE aE qr = 49 - 1 57., gr where q r denotes dg r ldt, &c., and E is the total energy expressed as a function of pi, qi,.

He rested his hand on the base of her neck, the warm energy of their bond moving through him.

She was surprised to feel a strange zap of energy, different than Gabriel's warmth but not unpleasant.

Deidre's body betrayed her, giving a full-form shudder at the rush of heat and energy.

Their energy made her skin tingle uncomfortably.

Cold energy traveled through her as she gripped the emerald.

It was followed by warm energy that Gabriel pushed into her body to calm her.

She wanted to tell him to leave, but whatever bond existed between them, it filled her with warmth and energy that quelled the meltdown she was about to have.

His energy sapped, the kid was sprawled half asleep across the race car bed.

He found some of his wired energy dissipating at the long walk and change of scenery despite knowing nothing good had ever come from a meeting with Sasha.

Her eyes were heavy, her anger draining her last bit of energy.

A blast of energy whipped by her, knocking her back, and the jaguar was sent flying.

The hot energy circulating through her body came from the large, olive-hued hands touching her.

The thrum of warm energy coursed through her again, and she felt again her destiny was tied with his.

Her thoughts drifted to the prisoner, the memory of his touch and the strange energy making her blood quicken.

The odd energy flowing between them held them both in silence for a long moment before he spoke.

The warrior before her had an intensity that made her breath catch, and the energy between them made her insides tingle.

She squirmed, unwilling to be defenseless with the tarantulas so close and uneasy with the warm energy flowing again between them.

She understood him and obviously felt the same energy he did when they touched.

His touch sent heated energy through her, and the nearness of his body made her tense.

The connection between them flowed with hot energy, the planet's life form itself bonding the two of them together at their touch.

She could feel his angry energy even over the viewer.

The initial sensations passed, and he breathed deeply, finally able to focus as his body adjusted to the feel of the energy flowing through him.

She didn't have the energy for a fight.

All she could think about was seeing, touching, kissing A'Ran and experiencing the odd energy that ran between them.

She felt the energy even from the distance and started forward.

Lana brought up the energy grids.

Everything this side of the Mississippi is working on solar energy, but not all the facilities are equipped with energy storage, and because it's fall, our energy collection is limited.

She listened for the familiar thrum of energy over her breathing.

She dragged the unconscious commander to the floor and replaced him in the seat before the energy terminal, assessing the damage done.

There was no running water, no food supplies, no energy whatsoever, just a deteriorating building with a score of insurgents and a small black box.

He was hot and sweaty, but he'd not yet been able to rid himself of the wired energy humming through his blood.

We're building a bigger battery to store the energy we generate from the river, but … Kelli shrugged.

There's no energy stored in it right now.

I'll check all the receivers and make sure the town will have energy before I go.

While they took away the fatigue and gave her energy, she could think of nothing but chocolate sundaes and pickles.

He managed to keep his body fluids up by frequent gulps to replenish his rapidly diminishing energy.

That was usually during the winter when he wasn't so busy and had more energy.

He must have had a lot of energy to keep up with two women.

Her cool energy surrounded him.

Here, magic emanated off of everything and filled her with its energy.

She was wired with a different kind of energy after the sparring session, one that made her remember all too clearly how she'd felt under his body.

Desire flew through her, hot and fast like the strange energy running between them.

With his healing magic and the first cheeseburger in her belly, Jenn felt renewed energy.

It explained the storm-cloud energy and how he'd broken her forearm with no effort.

Carnot, who were greatly impressed by his energy, sincerity and ability.

During his father's lifetime he had greatly distinguished himself by his administration of Transylvania, then a wilderness, which, with incredible patience and energy, he colonized and christianized.

A bent spring possesses energy, for it is capable of doing work in returning to its natural form; a charge of gunpowder possesses energy, for it is capable of doingwork in exploding; aLeyden jar charged with electricity possesses energy, for it is capable of doing work in being discharged.

The motions of bodies, or of the ultimate parts of bodies, also involve energy, for stopping them would be a source of work.

All kinds of energy are ultimately measured in terms of work.

Hence it is not surprising that, in those more subtle forms in which energy cannot be readily or completely converted into work, the universality of the principle of energy, its conservation, as regards amount, should for a long while have escaped recognition after it had become familiar in pure dynamics.

The smoother we make the pulley the more nearly does the amount of useful work which the weight is capable of doing approach ro foot-pounds, and if we take into account the work done against the friction of the pulley, we may say that the work done by the descending weight is ro foot-pounds, and hence when the weight is in its elevated position we have at disposal r o foot-pounds more energy than when it is in the lower position.

It should be noticed, however, that this energy is possessed by the system consisting of the earth and pound together, in virtue of their separation, and that neither could do work without the other to attract it.

The system consisting of the earth and the pound therefore possesses an amount of energy which depends on the relative positions of its two parts, on account of the latent physical connexion existing between them.

In most mechanical systems the working stresses acting between the parts can be determined when the relative positions of all the parts are known; and the energy which a system possesses in virtue of the relative positions of its parts, or its configuration, is classified as "potential energy," to distinguish it from energy of motion which we shall presently consider.

Newton had divined the principle of the conservation of energy, so far as it belongs purely to mechanics.

There was, however, even before Newton's time, more than a suspicion that heat was a form of energy.

After Newton's time the first vigorous effort to restore the universality of the doctrine of energy was made by Benjamin Thompson, Count Rumford, and was published in the Phil.

P. Joule to achieve; his experiments conclusively prove that heat and energy are of the same nature, and that all other forms of energy can be transformed into an equivalent amount of heat.

He argued that, if heat be energy, then, when it is employed in doing work, as in a steam-engine, some of the heat must itself be consumed in the operation.

Mayer made an assumption the converse of that of Seguin, asserting that the whole of the work done in compressing the air was converted into heat, and neglecting the possibility of heat being consumed in doing work within the air itself or being produced by the transformation of internal potential energy.

In this experiment a great noise was produced, corresponding to a loss of energy, and Joule endeavoured to determine the amount of energy necessary to produce an equal amount of sound from the string of a violoncello and to apply a corresponding correction.

A metal vessel was placed in a calorimeter and air forced into it, the amount of energy expended in compressing the air being measured.

Assuming that the whole of the energy was converted into heat, when the air was subjected to a pressure of 21.5 atmospheres Joule obtained for the mechanical equivalent of heat about 824.8 foot-pounds, and when a pressure of only 10 .

By continuing this process every unit of mass which enters B will carry with it more energy than each unit which leaves B, and hence the temperature of the gas in B will be raised and that of the gas in A lowered, while no heat is lost and no energy expended; so that by the application of intelligence alone a portion of gas of uniform pressure and temperature may be sifted into two parts, in which both the temperature and the pressure are different, and from which, therefore, work can be obtained at the expense of heat.

In the preface he states the position that "whenever, then, two gases are allowed to mix without the performance of work, there is dissipation of energy, and an opportunity of doing work at the expense of low temperature heat has been for ever lost."

In such experiments the molecular energy of a gas is converted into work only in virtue of the molecules being separated into classes in which their velocities are different, and these classes then allowed to act upon one another through the intervention of a suitable heat-engine.

If we could drive the engine so fast as to reduce C' to zero, the whole of the energy of the battery would be available, no heat being produced in the wires, but the horse-power of the engine would be indefinitely small.

The availability of the energy of electrical separation in a charged Leyden jar is also limited only by the resistance of conductors, in virtue of which an amount of heat is necessarily produced, which is greater the less the time occupied in discharging the jar.

The availability of the energy of magnetization is limited by the coercive force of the magnetized material, in virtue of which any change in the intensity of magnetization is accompanied by the production of heat.

In all cases there is a general tendency for other forms of energy to be transformed into heat on account of the friction of rough surfaces, the resistance of conductors, or similar causes, and thus to lose availability.

It is practically important to consider the rate at which energy may be transformed into useful work, or the horse-power of the agent.

It generally happens that to obtain the greatest possible amount of work from a given supply of energy, and to obtain it at the greatest rate, are conflicting interests.

A similar condition obtains in the steamengine, in which a great rate of working necessitates the dissipation of a large amount of energy.

To control the speed and Brakes absorb this energy, brakes have to be provided.

In electric cranes a useful method is to arrange the connexions so that the lifting motor acts as a dynamo, and, driven by the energy of the falling load, generates a current which is converted into heat by being passed through resistances.

When electric oscillations are set up in an open or closed electric circuit having capacity and inductance, and left to themselves, they die away in amplitude, either because they dissipate their energy as heat in overcoming the resistance of the circuit, or because they radiate it by imparting wave motion to the surrounding ether.

Accordingly this energy is rapidly dissipated and but few oscillations can take place.

If, however, the antenna is inductively or directly coupled to a condenser circuit of large capacity then the amount of energy which can be stored up before discharge takes place is very much greater, and hence can be drawn upon to create prolonged or slightly damped trains of waves.

When electric oscillations are set up in these two classes of electric radiators, the first class send out a highly damped wave train and the second a feeble damped wave train provided that they have sufficient capacity or energy storage and low resistance.

When oscillations are excited in this last circuit they communicate them to the antenna provided this last circuit is tuned or syntonized to the closed circuit, and the radiating antenna has thus a large store of energy to draw upon and can therefore radiate prolonged trains of electric waves.

The lower classes provoked disorders, which were very serious at Leghorn, and were only quelled by Guerrazzis energy.

Almost the only respect in which the Left could boast a decided improvement over the administration of the Right was the energy displayed by Nicotera in combating brigandage and the mafia in Calabria and Sicily.

Though sixty-eight years of age, Crispi possessed an activity, a rapidity of decision and an energy in execution with which none of his contemporaries could vie.

In the Armenian question Italy seconded with energy the diplomacy of Austria and Germany, while the Italian fleet joined the British Mediterranean squadron in a demonstration off the Syrian.

On the 17th of April a general railway strike was ordered by the union, but owing to the action of the authorities, who for once showed energy, the traffic was carried on, Other disturbances of a serious character occurred among the steelworkers of Terni, at Grammichele in Sicily and at Alessandria.

Baldwin raised them to great prosperity by his energy and foresight, and chiefly as a result of the active political and military support he rendered to the emperors Henry VII., Louis the Bavarian and Charles IV.

Brown and Escombe have shown that the amount of solar energy taken up by a green leaf may often be fifty times as much as it can utilize in the constructive processes of which it is the seat.

Whether the leaf is brightly or only moderately illuminated, the same relative proportions of the total energy absorbed are devoted to the purposes of composition and construction respectively.

The idea was till recently currently accepted, that anything which plants absorbed from without, and which went to build up their organic substance, or to supply them with energy, or to exert some beneficial influence upon their metabolism, coiistituted their food.

The absorption of these rays implies that the pigment absorbs radiant energy from the sun, and gives us some explanation of its power of constructing the carbohydrates which has been mentioned as the special work of the apparatus.

Supply and Distribution of Energy in PlantsIt is well known that one of the conditions of life is the maintenance of the process which is known as respiration.

These respiratory processes are associated with the liberation of energy by the protoplasm, energy which it applies to various purposes.
