The piston-cylinder device initially contains 0.05m3 of saturated liquid water at 30C. the spring is set such that the pressure of the water must be 100 kPa before the piston will move from the stops. When the total water volume is 0.2m3, the pressure is 1MPa. Heat is now added to the water at a rate of 5kw until the total water volume is 0.2m3.
