If the volume of a fixed mass of a gas is kept constant, the pressure of the gas
is inversely proprotional to its centigrade temperature
is inversely proportional to its absolute temperature
is directly proportional to its centigrade temperature
is directly proportional to its absolute temperature
remains constant also
Correct answer is D
Gay-Lussac's Law states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant.
