In a piston-cylinder assembly, 1 kg mass of Refrigerant 134a undergoes a process with initial pressure of 1 MPa and quality of 45% to a final temperature of 8C at which the refrigerant is saturated liquid. Can this process occur adiabatically? If yes, determine the work, in kJ, for an adiabatic process between these states. If no, determine the direction of the heat transfer. Kinetic and potential energy effects can be neglected.
