Question:

A frictionless piston-cylinder device contains 0.1 kg of refrigerant-12 as a saturated liquid. The piston is free to move, and its mass is such that it maintains a pressure of 200 kPa on the refrigerant. Due to heat transfer from the atmosphere, the temperature of the refrigerant gradually rises to the atmospheric temperature of 25oC. Calculate
(a) The work transfer.
(b) The heat transfer.
(c) The change of entropy of the refrigerant.
(d) The entropy generated in the system's universe.
