Step-by-step explanation:
Gay-Lussac Law:
This law states that pressure of the gas is directly proportional to the temperature of the gas at constant volume.
Mathematically,
(at constant volume )
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
So in order to decrease the pressure of the gas in container decrease the temperature of the gas present in the container due to which pressure of the gas will also get decrease as per as Gay-Lussac law.
