Gay Lussac's Law of Gaseous Volumes.

1.	Gay Lussac's Law of Gaseous Volumes.
Answer» Solution :This LAW was given by Gay Lussac in 1808. He observed that when combine or are produced in a chemical reaction they do so in a simple ratio by volume provided all gases are at same TEMPERATURE and pressure. Thus,100 mL of hydrogen combine with 50 mL of oxygen to give 100 mL of water VAPOUR. `{:("Hydrogen",+,"Oxygen",rarr,"Water",),(100mL,,50 mL,,100 mL,):}` Thus, the volumes of hydrogen and oxygen which combine together (i.e. 100 mL and 50 mL) BEAR a simple ratio of 2 : 1. Gay-Lussac.s discovery of integer ratio in volume relationship is actually the law of definite proportions by volume and stated earlier, was with RESPECT to mass.
