At low temperatures SA predominates, but as the temperature is raised S, increases; the transformation, however, is retarded by some gases, e.g.
1 3 2, p. 374), is an exceedingly stable colourless gas at ordinary temperatures, becoming solid at about -120° C. Sulphuryl chloride, SO 2 C1 2, first obtained in 1838 by Regnault (Ann.
The runners might encounter any kind of weather, including freezing temperatures, fog, rain, or snow.
Heated at 190-300° in a current of hydrogen it gives the oxide C0304, while at higher temperatures the monoxide is formed, and ultimately cobalt is obtained.
News, 1891, 63, p. 1); just above the boiling point the vapour is orange-yellow, but on continued heating it darkens, being deep red at 50o; at higher temperatures it lightens, becoming straw-yellow at 650°.
The pod was well-insulated; she didn't feel the three-thousand-degree temperatures a foot from her.
Ouray County was perfect for invigorating outdoor activity, with its crystal clear air and dry, windless temperatures just below freezing.
He wondered about the different temperatures of their bodies.
It is a bluish-black powder which at high temperatures decomposes into the metal, dioxide and oxygen.
Hansen showed that the microscopic appearance of film cells of the same species of Saccharomycetes varies according to the temperature of growth; the limiting temperatures of film formation, as well as the time of its appearance for the different species, also vary.
At 200 fathoms temperature falls in the same way from 58° to 55°, but below 250 fathoms temperatures are practically uniform to the bottom, 55 5° in the western basin and 56 5° in the eastern.
Temperatures above ioo° and below-15° are rare.
Thus at high temperatures a helium thermometer is of no special advantage.
At low temperatures, on the other hand, they find, using an initial pressure of 'coo mm., that the temperatures on the helium scale are measurably higher than on the hydrogen scale, owing to the more perfectly gaseous condition of helium.
It also possesses the power of combining with most metallic oxides at high temperatures, forming borates, which in many cases show characteristic colours.
Summer and mean winter temperatures may be set down as averaging not more than 20°, a range smaller than is found in most other parts of the world.
Temperatures radiates out a most brilliant white light.
Beyond this parallel the gradient is directed towards the north-west, and temperatures are much higher on the European than on the American side.
Below 500 fathoms the western centres of maximum disappear, and higher temperatures occur in the eastern Atlantic off the Iberian peninsula and north-western Africa down to at least 1000 fathoms; at still greater depths temperature gradually becomes more and more uniform.
The communication between the Atlantic and Arctic basins being cut off, as already described, at a depth of about 300 fathoms, the temperatures in the Norwegian Sea below that level are essentially Arctic, usually below the freezing-point of fresh water, except where the distribution is modified by the surface circulation.
The isothermals of mean surface temperature in the South Atlantic are in the lower latitudes of an cn- shape, temperatures being higher on the American than on the African side.
The climate is hot and humid in the lowlands and along the lower Parnahyba, but in the uplands it is dry with high sun temperatures and cool nights.
Rice is cultivated in low-lying, moist lands, where spring and summer temperatures are high.
In greenhouses where plants requiring very different optimum temperatures and illumination are kept together.
Equally disastrous are those climatic or seasonal changes which involve temperatures in themselves not excessive but in wrong sequence; how many more useful plants could be grown in the open in the United Kingdom if the deceptively mild springs were not so often followed by frosts in May and June!
The indirect geographical elements, which, as a rule, act with and intensify the direct, are mainly climatic; the prevailing winds, rainfall, mean and extreme temperatures of every locality depending on the arrangement of land and sea and of land forms. Climate thus guided affects the weathering of rocks, and so determines the kind and arrangement of soil.
(4) The grassy steppes or prairies where the rainfall is diminished and temperatures are extreme, and grass is the prevailing form of vegetation.
The average temperatures are: at Vyernyi (2405 ft.
High), for the year 46.4° F., for January 17°, for July 74°; at Przhevalsk (5450 ft.), for the year 36.5°; for January 23°, for July 63°; still higher in the mountains, at Naryn (6900 ft.) the average temperatures are only, for the year 43.
It is unstable at ordinary temperatures and rapidly decomposes into its generators on warming.
The lowest temperatures are experienced in January, the average being as low as 20° to 5° Fahr.
The surface-layers of this immense basin are heated in the summer up to temperatures of 55z° to 57° F., both close to the shores and at some distance from the mouth of the Selenga; but these warmer layers are not deep, and a uniform temperature of nearly 39° F.
The average temperatures are - year 51 0, January 26°, July 73° at Temir-khanshura (42° 49' N.; alt.
It is often taught that gneisses are the further stages of the crystallization of schists and belong to a deeper zone where the pressures and the temperatures were greater.
From 1879 to 1888 he was engaged on difficult experimental investigations, which began with an inquiry into the corrections required, owing to the great pressures to which the instruments had been subjected, in the readings of the thermometers employed by the "Challenger" expedition for observing deep-sea temperatures, and which were extended to include the compressibility of water, glass and mercury.
The highest mean temperatures for the whole year are those of Lenkoran (60.3°) and of Sukhum-kaleh and Poti (about 58°), and the lowest at Ardahan (5840 ft.), in the province of Kars, namely, 37.9°, and at Gudaur (7245 ft.), a few miles south of Kasbek, namely, 38.6°.
Thus its non-liability to freeze (when not absolutely anhydrous, which it practically never is when freely exposed to the air) and its nonvolatility at ordinary temperatures, combined with its power of always keeping fluid and not drying up and hardening, render it valuable as a lubricating agent for clockwork, watches, &c., as a substitute for water in wet gas-meters, and as an ingredient in cataplasms, plasters, modelling clay, pasty colouring matters, dyeing materials, moist colours for artists, and numerous other analogous substances which are required to be kept in a permanently soft condition.
The variations of temperature are very great in Siberia, amounting near the coast to more than 100° Fahr., between the mean of the hottest and coldest months, and to still more between the extreme temperatures of those months.
The temperatures at the head of the Persian Gulf approximate to those of northern India, and those of Aden to Madras.
The extreme temperatures in Siberia may be considered to lie between 80° and 90° Fahr.
These figures sufficiently indicate the main characteristics of the air temperatures of Asia.
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.
