Thermodynamics question?
Initially a rigid tank equipped with a resistance heater contains 5kg of saturated liquid water at
150 kPa. The heater is turned on for a period of time until 50% of the water by mass is vaporized.
Assume that the tank is insulated and determine the entropy change of the water through this
process in kJ/W. Sketch the process on a T-s diagram with respect to the dome and a line of
constant pressure.
