Question: 5 - 8 A frictionless piston - cylinder device initially contains 5 0 L of saturated liquid refrigerant - 1 3 4 a . The

5-8 A frictionless piston-cylinder device initially contains 50 L of saturated liquid refrigerant-134a. The piston is free to move, and its mass is such that it maintains a pressure of 500 kPa on the refrigerant. The refrigerant is now heated until its temperature rises to 70C. Calculate the work done during this process. Answer: 1600 kJ
