Life of Amadeo Avagadro
In this writing essay, I will write about Amedeo Avogadro. Firstly, I will write about his early life, then I will write about his education life and at the end I will about Avagadro’s Law. While writing my essay, I will touch upon some points about Avagadro’s private life.
Amedeo Avogadro was born August 9, 1776 and died July 9, 1856. His whole life passed in Turin, Italy. His family was a family of distinguished lawyers. He followed his family’s foot steps in his education. At the age of 20, he graduated in ecclesiastical law and in the following years he started to practice law. He was a lawyer but he was interested also in the natural sciences. He started his private studies on the natural sciences in 1800 and, in 1809, he started teaching what he learned from his studies about the natural sciences in a high school, called as liceo in his time, in Vericelli. He wrote a concise note in Vericelli, in which he declared his most famous hypothesis called Avagadro’s Law. After writing his hypothesis he sent it to a journal called, De Lamétherie’s Journal de Physique, de Chemie et d’Histoire naturelle. The journal published his first law on its July 14th edition under the following title, “Essai d’une manière de déterminer les masses relatives des molecules élémentaires des corps, et les proportions selon lesquelles elles entrent dans ces combinaisons”. After his hypothesis called Avagadro’s Law, he published another hypothesis about gas densities in the Jun 1811 edition of a journal called as Journal de Physique. In 1841, Avogadro completed and published his 4-volume work with the following title, “Fisica dei corpi ponderabili, ossia Trattato della costituzione materiale de’ corpi”.
There is not much information about Avagadro’s private life. It is known that he had six children and he married just once. He was a religious man and he was Christian.
Avagadro says that equal volume of gases, at the same temperature and pressure, contain the same number of molecules. Until 1858, people generally didn’t accept Avagadro’s law. Avagadro believed that every particle is composed of simpler particles called molecules and molecules are composed of still simpler units called atoms. In honor of Avogadro’s theories, the number of molecules in a mole is called as “Avagadro’s Number” or “Avagadro’s Constant”. Avogadro’s number has been determined to be 6.023×1023 molecules per gram-mole.
