Question

Please only answer number TWO.

1. Steam is contained in a 2-L volume at a pressure of 2.0 MPa and a temperature of 400 C. If the pressure is held constant by expanding the volume while 20 kj of heat is added, what is the final temperature and the work done? 2. A 1-m' rigid volume contains water at 90"C with a quality of 0.B. Determine the final temperature if 600 kj of heat are added. 3. Dry saturated steam at 200 bar expands isothermally and reversibly to a pressure of 10 bar. Calculate the heat supplied and the work done per kg of steam.
