In the year 1880, Joseph Gay-Lussac (1778 -1850) had established that whenever different gases combine chemically, often volumes of the combining gases are achieved in the ratio of simple integers. By getting this observation, Lorenzo Roman Amadeo Carlo Avogdra (1776-1856) brings a result into focus that the number of molecules in a given volume of gas at a given temperature, is got same for all gases. He had achieved the experiment but how it happens, he was unable to prove it therefore this statement became known as Avagodro’s Hypothesis and in respect of the number which he sought for calculating known as Avogadro’s number.
For determining the Avogadro’s number, firstly it is so necessary to determine the characteristic size and mass of a molecule.
In value of the Avogadro’s number, Johann Josef Loschmidit recognized
a method for determining the diameter of a gas molecule from the density of the liquefied gas and the mean free path of a molecule in the gaseous phase. By the result of the discovery of this method, Avogadro’s number is called as Loschmidt’s Number in German speaking Countries. Besides it, Gay-Lussac’s Law also develop some confusion as result of it each scientist has its own determination. According to the conclusion of the Gay-Lussac that gases combine in very low proportions as well as the apparent contraction which is achieved in volume get a combination and the particular combination has also a simple relation with the volume of the gases. About the relationship, it is known as the law of combining volumes and in term of Gay-Lussac’s law also. In the Law, Gay-Lussac pointed out that his laws of the simple regularities were realized only for gases.
Law of Gay-Lussac is only for gas, so it behaves in the simplest and most universal manner. But on another side English Chemist John Dalton’s Laws offer the importance of definite and multiple proportions in chemical composition which is formulated in the same period. As well as it is referred for combining weights but not for volumes. These two differences create an approach amongst each scientist to develop a skeptical approach in respect of the result of these two laws. As well as, the scientists of these two laws also don’t reach at mutual understanding. For providing a combination, the Italian Physicist Amedeo Avogadra showed by which way results of Gay-Lussac and Dalton could be reconciled and it is said so by the Encyclopedia Britannica. This is the current reports of Avogadro’ Hypothesis. For more information, keep eyeing on currentreports.info.
