A piston cylinder device initially contains 0.05 m^3 of saturated liquid water at 30 C. The spring is set such that the pressure of the water must be 100 kPA before the pistn will move from the stops. When the total water volume is 0.2 m^3, the pressure is 1 MPa. Heat is now added to the water at a rate of 5 kW until the total water volume is 0.2 m^3. What's the final temperature of the water? How much work is done by the water? How much time is required to complete this process? What is the entropy change of the water?
