A weighted piston-cylinder device (pressure is not constant) initially contains 1.2 kg saturated liquid water at 190oC. Now heat is transferred to the water until the volume quadruples (increase four times) and the cylinder contains saturated vapor only. Determine: a) The final volume of the tank. b) The final temperature and pressure. c) The internal energy change of the water.
