A piston$$cylinder device contains $0\mathrm{.}54$ kg of steam at $300\backslash$deg C and $0\mathrm{.}5$ MPa. Steam is cooled at constant pressure until one$-$half of the mass condenses. Use data from the steam tables.

Show the process on a T$-$V diagram.Find the final temperature.Determine the volume change. $($Round the final answer to three decimal places.$)$
