A piston-cylinder device with a set of stops initially contains 0.6 kg of steam at 1.0 MPa and 400 C. The location of the stops corresponds to 40 percent of the initial volume. Now the steam is cooled. Determine the compression work if the final state is (a) 1.0 MPa and 250 C and (b) 500 kPa. (c) Also determine the temperature at the final state in part (b).

Repeat Problem 3, but this time, treat the steam as an ideal gas
with cp = 2.083 kJ/kg-K, which is its value at about 700 K. (You
will need to determine Rg = Ru/MWwater, with MWwater = 18.0
kJ/kg-K, as well as k = cp/cv). You’ll find that the ideal gas
model is not too bad for water vapor under these conditions.
