An Ideal gas originally at a temperature T1 and pressure P1 is compressed reversibly against a piston to a volume equal to one-half its original volume. The temperature of the gas is varied during the compression so that at each instant the relation P = AV is satisfied, A = Constant. Draw a diagram of the process in the P-V plane.
