516 ページ - When a ray of light passes from one medium to another, it is refracted so that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities in the two media.
84 ページ - The immediate cause of the phenomena of heat then is motion, and the laws of its communication are precisely the same, as the laws of the communication of motion.
286 ページ - C. in 5J minutes: and assuming as the unit of heat the quantity required to raise the temperature of 1 gram of water from 0°...

In the second class are placed bismuth, antimony, zinc, tin, cadmium, sodium, -mercury, lead, silver, copper, gold, arsenic, uranium, rhodium, iridium, tungsten, phosphorus, iodine, sulphur, chlorine, hydrogen, and many of their compounds. Also, glass free from iron, water, alcohol, ether, nitric acid, hydrochloric acid, resin, wax, olive oil, oil of turpentine, caoutchouc, sugar, starch, gum, and wood. These are diamagnetic.
82 ページ - Fig. 661. which is shown at p, their axes being supported on friction-wheels dd, and the pulleys were connected by fine twine with a wooden roller r, which, by means of a pin, could be easily attached to or removed from the friction apparatus. The mode of experimenting was as follows : The temperature of the frictional apparatus having been ascertained ; and the weights wound up, the roller was fixed to the axis, and the precise height of the weights ascertained ; the roller was then set at liberty,...
164 ページ - It is necessary to bear this in mind in order to understand why the air which is absorbed by water out of the atmosphere differs in composition from atmospheric air.
85 ページ - ... arising from all the motions of the particles of the gas. From this it follows that the quantity of heat which must be added to a gas of constant volume in order to raise its temperature by a given amount, is constant and independent of the temperature. In other words, the specific heat of a gas referred to a given volume is constant, a result which agrees with this experiments of Regnault, mentioned at p.
74 ページ - At temperatures above 31° no apparent liquefaction of carbon dioxide or separation into two distinct forms of matter can be effected, even under a pressure of 300 or 400 atmospheres. Similar results are obtained with nitrous oxide. It appears indeed that there exists for every liquid a temperature, called by Andrews the
87 ページ - The production and consumption of heat which accompany changes in the state of aggregation, or of the volume of bodies, are easily explained, according to the preceding principles, by taking account of the work done by the acting forces.
739 ページ - Oudemanns,* the best material for the preparation of stearic acid is shea-butter, which contains about 70 per cent, stearic, and 30 per cent, oleic acid, but no other solid fatty acid. On the large scale, impure stearic acid is prepared for the manufacture of stearin-candles, by saponifying some of the harder fats, generally with lime. The resulting lime-soap, decomposed by sulphuric acid, yields a mixture of fatty acids, which are pressed, first in the cold, and afterwards at a higher temperature,...
