Consider a transformation from point A to B in a two-step process. First, the pressure is lowered from 13 MPa at point A to a pressure of 2 MPa, while keeping the volume at 3.1 L by cooling the system. The state reached is labeled C. Then the system is heated at a constant pressure to reach a volume of 9.5 L in the state B. (Assume the system consists of a monatomic ideal gas.)
