A piston cylinder device initially contains compressed liquid water at 20degreesC and 200kPa. It is heated in an isobaric process (process 1) until it contains only saturated liquid. At this point it occupies a volume of 0.0021m3.

a) How much heat does process 1 require?

b) The saturated liquid water is now heated in a second isobaric process (process 2) until it contains only saturated vapor. How much heat (kJ) did this process require?

c) How much Boundary work (kJ) did the system perform on the surroundings?

d) More heat is added in an isochoric process (process 3) until the temperature is 300degreesC. What is the pressure (kPa) of the gas now?

e) For process 3, how much energy (kJ) did this third heating process require?
