Piston-Cylinder Device

A piston-cylinder device contains 5 kg of refrigerant-134a at 800 kPa and 60 degrees Celsius. The refrigerant is now cooled at constant pressure until it exists as liquid at 20 degrees Celsius. Determine the amount of heat loss and show the process on a T-v diagram with respect to saturation lines.

Please show steps.
