A closed system contains 2 kg of saturated steam at 3 MPa. The steam expands in a reversible process which can be represented by a straight line in a Ts Diagram. The final condition of the steam is 150 kPa and 200°C. The surroundings are constant temperature of 20°C. A) Sketch Ts diagram (if possible) b) calculate heat transferred from system. c) calculate work done by system. and d) calculate the entropy change of the surroundings.
