A cylinder fitted with a movable piston contains propane, initially at 67oC and 50 % quality, at which point the volume is 2 L. The piston has a cross-sectional area of 0.2 m2. The external force on the piston is now gradually reduced to a final value of 85 kN, during which process the propane expands to ambient temperature, 4oC. Any heat transfer to the propane during this process comes from a constant-temperature reservoir at 67oC, while any heat transfer from the propane goes to the ambient. It is claimed that the propane does 30 kJ of work during the process. Does this violate the second law?
