A piston-cylinder device with a set of stops initially contains 0.6 kg of steam at 1.0 MPa and 400°C. The loca- tion of the stops corresponds to 40 percent of the initial volume. Now the steam is cooled. Determine the compres- sion 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). Steam 0.6 kg 1 MPa 400°C FIGURE P4-5
