1-A piston-cylinder device with a set of stops contains 10 kg of refrigerant-134a. Initially, 8 kg of the refrigerant is in the liquid form, and the temperature is 8°C. Now heat is transferred slowly to the refrigerant until the piston hits the stops, at which point the volume is 400 L. Determine (a) The temperature when the piston first hits the stops and (b) The work done during this expansion process. Also, show the process on a P-V diagram.

0.4 kg of Refrigerant 134a initially fills a piston–cylinder device with a volume of 15 L at a pressure of 400 kPa. The cylinder is connected to a supply line through a valve. R-134a is flowing in the supply line at 900 kPa and 45°C. The valve is opened, and R-134a is allowed to enter the cylinder. The valve is closed when the volume of the cylinder is triple and the temperature in the cylinder reaches 15°C. During the process,...
