...gases. One step further leads us to admit AVOGADEO'S HYPOTHESIS : Equal volumes of different gases (measured at the same temperature and pressure) contain the same number of individual particles. If this hypothesis is correct, then : 1. The densities of different gases must...

...common measure of molecules. If it be true, as Avogadro taught, that " equal volumes of different gases at the same temperature and pressure contain the same number of molecules," then those quantities of all substances which fill the same volume in 1 English translations of both...

...hypothesis. — It is assumed that equal volumes of all gases, independently of their chemical character, at the same temperature and pressure, contain the same number of molecules. This was put forth as a hypothesis by Avogadro in 1811, but it may also be deduced from the kinetic...

...volumes of all gases are equal, and Avogadro's theorem states that equal volumes of different gases at the same temperature and pressure contain the same number of molecules. The second general law is that all chemical changes take place between fixed definite proportions by...

...overcome by a hypothesis, which AVOGADRO enunciated in 1811, to the effect that equal volumes of all gases at the same temperature and pressure contain the same number of molecules. AVOGADRO further supposes that the molecules of oxygen, hydrogen, chlorine, and other elements consist...

...gathered, :';•• 'in both the chemical and physical study of gases, that equal volumes of gases measured at the same temperature and pressure contain the same number of molecules (Avogadro's Law). It follows that the number of times that a volume of one gas, A, is heavier than...

...According to AVOGADKO'S law (" Inorganic Chemistry," 31, 32, and 35), equal volumes of diiferent gases measured at the same temperature and pressure contain the same number of molecules. From this it follows that the weights of the molecules of these gases must stand in the same relation...

...evidence in harmony with it. According to Avogadro's hypothesis a liter of hydrogen and a liter of oxygen at the same temperature and pressure contain the same number of molecules, though we do not know how many. Suppose, however, that each liter contained 1000 molecules. A liter...

...compared with the distance separating them, Avogadro inferred that equal volumes of all perfect gases at the same temperature and pressure contain the same number of molecules. If the densities of two different gases under the same pressure and temperature be represented by p...

...According to AVOGADRO'S law (" Inorganic Chemistry," 31, 32, and 35), equal volumes of different gases measured at the same temperature and pressure contain the same number of molecnles. From this it follows that the weights of the molecules of these gases must stand in the...
