Apiston-cylinder device initially contains 1.2 m³ of saturated water vapor at 600 kpa. at this state, the piston is resting on a set of stops, and the mass of the piston is such that a pressure of 1000 kpa is required to move it. heat is now slowly transferred to the steam until the volume doubles. show the process on t-v and p-v diagrams with respect to saturation lines and determine (a) the final temperature, (b) the work done dur
