Page 120 - ... the following general law^, that, under equal circumstances of temperature, water takes up, in all cases, the same volume of condensed gas as of gas under ordinary pressure. 'But, as the spaces occupied by every gas are inversely as the compressing force, it follows, that water takes up, of gas condensed by one, two, or more additional atmospheres, a quantity which, ordinarily compressed, would be equal to twice, thrice, &c.
Page 89 - The rates of diffusion of two gases are inversely proportional to the square roots of their densities.
Page 58 - The volume of any gas is inversely proportional to the pressure to which it is subjected.
Page 39 - Lastly, the GRAMME, which is the weight of a cubic centimetre of distilled water at its...
Page 114 - The specific gravity of any substance is the number found by dividing the weight of the substance by the weight of an equal bulk of water.
Page 112 - It will be seen from the above definition that the specific heat of a substance is the ratio between the amount of heat required to raise the temperature of the substance 1°, and the amount of heat required to raise the temperature of the seme weight of water 1°.
Page 59 - It is further supposed by chemists that at a given pressure and temperature equal volumes of all gases, whether simple or compound, contain the same number of molecules. Thus, a cubic foot of hydrogen, a cubic foot of air, a cubic foot of steam, all contain the same number of molecules at the same temperature and pressure. Suppose...
Page 53 - Law, which states that when the temperature is constant the volume of a gas is inversely proportional to the pressure.
Page 120 - Boyle discovered that the volume of a gas is inversely proportional to the pressure if the temperature is constant.
Page 53 - ... mouth, owing to the small blood-vessels, unsupported by the atmospheric pressure, being unable to withstand the forcible propulsion of the blood through the system. The relation according to which the density of the air diminishes in ascending...
