...molecular theory. It is more general, and includes the other two. It declares that equal volumes of all gases, under the same conditions of temperature and pressure, contain the same number of molecules. t&n&eAj Liquids are distinguished from^eS4e chiefly in having a definite surface. Their particles have...

...number of simple gases. But if equal volumes of these gases, measured, let it be well understood, under the same conditions of temperature and pressure, contain the same number of atoms, it is evident that the weights of these equal volumes should represent the weights of the atoms....

...early as 1811, as follows : "Equal volumes of all substances when in the state of gas, and under like conditions of temperature and pressure, contain the same number of molecules." This is known as Avogadro's law. The law of Avogadro cannot be directly proved, but it is indirectly established...

...not fail to suggest to Ampere the following hypothesis : EQUAL VOLUMES OF ALL GASES, MEASURED UNDER THE SAME CONDITIONS OF TEMPERATURE AND PRESSURE, CONTAIN THE. SAME NUMBER OF MOLECULES OF THE SUBSTANCE. 382. The following illustration may serve to make this clearer: Take three glass...

...Cn+8HN03=3 Cn(N03)2+2 NO+ 4H..O. 7. Equal volumes of all substances in the gaseous state, and under the same conditions of temperature and pressure contain the same number of molecules. By means of this principle the atomic weights of elements and the molecular formulae of compounds have...

...is more general, and includes the other two. It declares that equal volumes of all gases under the 1 same conditions of temperature and pressure contain the same number of molecules. A liquid has a definite surface. It can be only very slightly compressed, and obeys neither of the...

...relating to the physical properties of gases, led Avogadro to the conception ^ that equal volumes of all gases under the same conditions of temperature and...pressure contain the same number of molecules. This is known as Avogadro's hypothesis. It has been tested in a great many ways, but has always asserted...

...conclusions in regard to the relative weights of atoms. Avogadro's hypothesis that equal volumes of all gases under the same conditions of temperature and pressure contain the same number of molecules was suggested by a study of the physical properties of gases and a comparison of the weights of equal...
