Gay-Lussacís Law

 

Gay-Lussacís law addresses the proportional relationship between the pressure and thermodynamic temperature of a gas under controlled conditions. It can be stated as follows: For a constant amount of an ideal gas at a constant volume, the pressure exerted by the gas is directly proportional to the thermodynamic temperature of the gas.

 

Gay-Lussacís law discovered by French chemist Joseph Louis Gay-Lussac (1778Ė1850) is also referred as Gay-Lussacís law of pressure-temperature to distinguish it from Gay-Lussacís law of combining volumes. It has also been known as the law of Charles and Gay-Lussac since Gay-Lussac attributed it to unpublished data of Jacques Charles from 1780s. Gay-Lussacís law is also mentioned as Amontonsí law due to beforehand investigations of Guillaume Amontons.
