A frictionless piston-cylinder contains H2O initially at 1000 kPa and 200C. The system is slowly cooled at constant pressure to 20C.
a. Determine the temperature at which you would expect two phases to exist
b. Calculate the work for the entire process
c. Calculate q for this process
d. Show the process on P-v and T-v diagrams including the saturation curve on each diagram.
