A pistoncylinder device contains 5 kg of saturated water
Chapter 7, Problem 7228(choose chapter or problem)
A pistoncylinder device contains 5 kg of saturated water vapor at 3 MPa. Now heat is rejected from the cylinder at constant pressure until the water vapor completely condenses so that the cylinder contains saturated liquid at 3 MPa at the end of the process. The entropy change of the system during this process is (a) 0 kJ/K (b) 23.5 kJ/K (c) 212.5 kJ/K (d) 217.7 kJ/K (e) 219.5 kJ/K
