A quantity of helium gas at room temperature is placed in a cylinder with a moveable piston. If the cylinder is locked in place so that the volume cannot change and a quantity of heat Q0Q0 is added to the gas, the temperature of the gas increases by Î"T0Î"T0. Now the gas is cooled to its original temperature and the piston is unlocked so that the gas is free to expand. If the pressure exerted on the gas by the piston is held constant and the same quantity of heat Q0Q0 is added to the gas, what will be the temperature change of the gas?
