A cylinder contains 2 moles of an ideal monatomic gas that is initially at state A with a volume of 1.0 x

10-2 m³ and a pressure of 4.0 x 105 Pa. The gas is brought isobarically to state B, where the volume is 2.0

x 10-2 m³. The gas is then brought at constant volume to state C, where its temperature is the same as at

state A. The gas is then brought isothermally back to state A.
