Water initially at 200 kpa and 3008c is contained in a piston-cylinder device fitted with stops. the water is allowed to cool at constant pressure until it exists as a saturated vapor and the piston rests on the stops. then the water continues to cool until the pressure is 100 kpa. on the t-v diagrams sketch, with respect to the saturation lines, the process curves passing through both the initial, intermediate, and final states of the water. label the t, p and v values for end states on the process curves. find the overall change in internal energy between the initial and final states per unit mass of wate
