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. a. Determine the heat transfer during the initial coolingto the stopsusing enthalpies
b. Determine the heat transfer during the finalcoolingwhen the volume is constantusing internal energies.
c. Determine the initialinternal energy, and using this determine the work for the specific volumes
d. Calculate the work during the initial cooling by determing specific volumes.
