Transcribed Image Text:(Q1) Water initially at 200 kPa and 300°C 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 water.
