  1. PAL 3/19/12 • Consider ½ lbm of liquid water at 350oF and 134.63 psia. The water then all vaporizes at constant pressure. • Is work done on the water or by the water? • How much? • Does the water’s internal energy increase or decrease? • By how much? • Does heat flow into or out of the water (real answer this time, no gut!)? • How much?

  2. Consider ½ lbm of liquid water at 350oF and 134.63 psia. The water then all vaporizes at constant pressure. • Find the change in enthalpy of the water in this process. • compare your answer to #1 (f).
