A mass of 0.1 kg of water, initially at 250 oC and 500 kPa is contained in a rigid container. The water is allowed to cool to the ambient temperature of 25oC. (a) Sketch the process on the P-v ant T-v diagrams, showing the saturation lines, as well as the isotherms passing through the initial and final states. Label the last with the appropriate temperature values, and label all relevant points. (b) Calculate the heat transfer during the process. (c)Calculate the total entropy change for the system and its surroundings.
