A piston-cylinder containing liquid water at 20 Celsius undergoes a constant pressure process at 25 bars, to a final temperature of 400 Celsius. Draw the T-v diagram. Determine the work and heat transfer for each of the three parts of the process (a) initial to saturated liquid, (b) saturated liquid to vapor and (c) saturated vapor to final state.
