A free piston-cylinder system initially contains 8 kg of saturated liquid water at 275 kPa (initial state). The water in the cylinder is gradually heated until all liquid has been vaporized to saturated vapor (final state). Determine the following: a) The volume of water in cylinder at initial and final state. b) The boundary work during this process. c) The heat transfer Q during this process. d) Locate both the initial and final states on a T-v diagram, label the temperature and specific volumes of both the states.
