A piston-cylinder device initially contains 0.15-kg steam at 3.5 MPa, superheated by 5°C. The steam loses heat to the surroundings and the piston moves down, hitting a set of stops at which point the cylinder contains saturated liquid water. The cooling continues until the cylinder contains water at 200°C. Steam 0.15 kg 3.5 MPa Q
