A rigid tank contains 1 kg of H2O at 1000 kPa, 1000oC. Heat is now transferred to the surroundings and the steam gradually cools down to a temperature of 30oC. Use the PC state daemon to determine a series of states at intermediate temperatures, while holding the volume and mass constant. Plot how the pressure, internal energy (E), and entropy (S) change as a function of temperature. Compare these results with the results of problem 1-2-16 [PV].
