Amedo Avogadro was an outstanding Italian physicist who lived in the 18th century.
Although he had followed the family tradition by studying law, he gradually lost interest in legal matters. He found science was much more intellectually stimulating.
Mathematics, and physics, in particular attracted his logical mind. Avogadro is chiefly remembered for his molecular hypothesis, first presented in 1811. He stated that equal volumes of different gases contain an equal number of molecules, provided they are at the same temperature and pressure.
Amedeo Avogadro was a great scientist who made important contributions to physics. However, he never received any awards for his discoveries.
Avogadro’s hypothesis gained acceptance only after his death as people did not recognize their significance. In honour of his contribution to molecular theory, the number of molecules in one mole was named Avogadro’s number.
