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,...
