...pressure. From this fact it follows, as a mathematical consequence, that equal volumes of all gages, under the same conditions of temperature and pressure, contain the same number of molecules. This deduction, which is of great importance in the theory of chemistry, ia called the Law of Ampe"re....

...that is to say, the kinetic energy in each volume is the same. According to Avogadro's hypothesis, equal volumes of all gases under the same conditions of temperature and pressure, contain an equal number of molecules, however much the weight of these molecules may vary ; therefore the average...

...was suggested by Avogadro in 1811, and independently by Ampere in 1813, that all gases, when under the same conditions of temperature and pressure, contain the same number of molecules per unit of volume. This assumption also explains the observed fact that the densities of gases are...

...system of molecular and atomic weights. The law of Avogadro states that equal volumes of different gases under the same conditions of temperature and pressure contain the same number of molecules. This statement is sometimes altered by students, and even by teachers, into ' gaseous molecules have...

...volumes uniting bear a simple ratio to one another and to the volumes produced. The theory is that equal volumes of all gases under the same conditions...and pressure contain the same number of molecules. It follows then that the weights of the molecules of a gas will be proportional to the density of the...

...1776-1856. Prof, of physics at Turin 1820. He announced 1811 the law that equal volumes of different gases under the same conditions of temperature and pressure contain the same number of molecules. Avoirdupois. English standard weights for everything except medicines, precious metals, and gems, for...

...allied to this was formulated by Avogadro in 1811, and is known as " Avogadro's Law." It stated that " equal volumes of all gases under the same conditions...and pressure contain the same number of molecules." From this it follows that the molecular weights of gases are proportional to their densities; that...

...importance. The statement of the hypothesis is usually called Avogadro's Law. It is that equal volumes of gases under the same conditions of temperature and pressure contain the same number of molecules. We really made this assumption when discussing the number of atoms in a molecule of oxygen and in a...

...on Gay-Lussac°s law of volumes, in order to connect the chemical and physical properties of gases. Equal volumes of all gases, under the same conditions...and pressure, contain the same number of molecules. The general equation, T = T0 can be given a simpler form if we suppose the symbols on the right-hand...

...together with others 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 manb'er of molecules, the molecule of a substance being the. smallest particle of that substance as...
