One kilogram of water contained in a piston–cylinder assembly, initially saturated vapor at 300 kpa, is condensed at constant pressure to saturated liquid. consider an enlarged system consisting of the water and enough of the nearby surroundings that heat transfer occurs only at the ambient temperature of 25°c. assume the state of the nearby surroundings does not change during the process, and ignore kinetic and potential energy effects. for the enlarged system, determine the heat transfer, in kj, and the entropy production, in kj/k.
