A piston-cylinder device with a set of stops initially contains 0.3 kg of steam at 1.0 MPa and 400°C. The location of stops indicates 60% of the initial V. Now the steam is cooled. Compute the compression work if the final state is (a) 1.0 MPa and 250°C and (b) 500 kPa. (c) Find the final T in part (b).
