10 kg of superheated water vapor at 200 °C and 1.2 MPa is condensed isobarically to a saturated mixture with a quality of x = 0.2 in a free piston-cylinder device:
(a) Calculate the volume and total internal energy of water at the initial and final state.
(b) Draw a T-v diagram indicating the process.
(c) Calculate the heat transfer and the work done during this process, in kJ.
