R-22 in a piston/cylinder has mass 1 kg and temp. 10°C with a volume of
0.02 m3 . Initially (state 1) the piston rests on stops with the top surface open to the atmosphere, Po, so a pressure of 1600 kPa is required to lift it (state 2). Hint: v1 = v2
i) To what temperature should the R-22 be heated to lift the piston? Draw the process from initial state to lifting on P-v and T-v diagrams.
ii) If it is heated to saturated vapor find the final volume, heat transfer, and work transfer.
