Extracted text: 3- The water in the form of superheated steam with a mass of 1 kg at a pressure of 500 kPa and a temperature of 500 ° C in the piston-cylinder assembly is first cooled to a temperature of 120 °C in a fixed volume and then the water is cooled and condensed at a constant temperature until it becomes a saturated liquid. a) Draw the T-v diagram of the states. b) Find the work done during the state changes. c) Find the heat transfer from the piston and cylinder assembly to the environment. Note: Changes in kinetic and potential energies are negligible
