A closed piston-cylinder assembly as shown in Figure 1 filled with 12 kg of Refrigerant-22 has aninitial temperature of T1 = (10X14) °C and pressure P1. The refrigerant is brought to a state whereits temperature reaches 0°C through a two-step process by removing heat into the surrounding.The piston moves freely without friction keeping the pressure in the piston equal to P1 until thepiston hits the stopper. Both kinetic and potential differences of the refrigerant are neglected.Piston-Piston-PistonState 1State 2State 3
