A piston-cylinder device contains 5 kg of refrigerant-134a at 0.7 MPa and 60°C. The refrigerant is now cooled at constant pressure until it exists as a liquid at 24°C. If the surroundings are at 100 kPa and-24°C, determine: (a) the exergy of the refrigerant at the initial and the final states and
(b) the exergy destroyed during this process.
