One mole of an ideal gas is originally at p0, V0, and T0 . The gas is heated at constant volume to 2T0, then allowed to expand at constant temperature to 2V0, and finally it is allowed a cool at constant pressure to T0, the net entropy change for this ideal gas is (A)∆S = (5R/2) In 2. (B)∆S=5R/2. (C)∆S = R In 2. (D)∆S=3R/2. (E) ∆S = 0.
