A frictionless piston-cylinder with a set of stops is initially filled with 50-L of refrigerant 34-a at 1400 KPa and 145°C. The mass of the piston is such that it

will not float until the pressure reaches 450 kPa. The refrigerant is cooled in a freezer kept at -10°C. A. Sketch the process in a P-v diagram, indicating both states with respect to the saturation lines. Make sure to show the constant temperature lines as well. (15 points) B. Calculate the boundary work done during the process (10 points): C. Determine the amount of heat transfer (10 points):
