What is Gay-Lussac’s Law?
Gay-Lussac’s law states that the pressure exerted by a gas varies directly with the absolute temperature of the gas if the mass of the gas is fixed and the volume is constant. i.e. The pressure exerted by a gas is proportional to the temperature of the gas at constant volume.
P ∝ T
Adding proportionality constant k,
P = kT
Now, at temperature T1 and pressure P1
P1 = kT1…(1)
Also, at temperature T2 and pressure P2
P2 = kT2…(2)
Now, combining eq(1) and eq(2)
P1 / T1 = P2 / T2
P is the pressure exerted by the gas
T is the absolute temperature of the gas
Gay Lussac’s Law
Gay Lussac’s is one of the Ideal gas laws that relates the pressure of the gas with its absolute temperature when its volume is kept constant. The basic statement of Gay Lussac’s Law is, the pressure produced by a gas is directly proportional to its temperature if mass and volume are kept fixed. Gay Lussac’s Law has wide application in sciences and also in our everyday life. Gay Lussac’s Law as the name suggests was given by the French chemist Joseph Gay-Lussac in the year 1808.
