(Solution) - A piston cylinder device contains 5 kg of refrigerant -(2025 Original AI-Free Solution)

Paper Details

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 energy of the refrigerant at the initial and the final states and
(b) The energy destroyed during this process.
