A piston-cylinder device initially contains 1.4 kg of refrigent-134a at 140 kPa and 20 °C. Heat is now transferred to the refrigerant, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 180 kPa. Heat transfer continues until the temperature reached 120 °C. Assuming the surroundings to be at 25 °C and 100 kPa, determine (a) the work done, (b) the heat transfer, (c) the exergy destroyed, and (d) the second-law efficiency of this process.
