Applying the Entropy Balance: Closed SystemsOne lb of
Chapter 6, Problem 38P(choose chapter or problem)
One lb of water contained in a piston–cylinder assembly, initially saturated vapor at 1 atm, is condensed at constant pressure to saturated liquid. Evaluate the heat transfer, in Btu, and the entropy production, in \(\mathrm{Btu} /{ }^{\circ} \mathrm{R}\), for
(a) the water as the system.
(b) an enlarged system consisting of the water and enough of the nearby surroundings that heat transfer occurs only at the ambient temperature, \(80^{\circ} \mathrm{F}\).
Assume the state of the nearby surroundings does not change during the process of the water, and ignore kinetic and potential energy
