Refrigerant 134a inside an insulated piston-cylinder assembly initially occupies 0.017 m at 0.6 MPa, 40°C. The refrigerant expands to a final state of pressure 300 kPa. The work done during this expansion process is claimed to be 5.512 kJ. What is the mass of refrigerant? (kg) Can the claimed amount of work be true? a)
