$...$seen in the figure, the piston in a cylinder is

suspended by a spring as shown in the figure. The pressure inside the

cylinder always changes in proportion to its volume until the piston

touches the stoppers. When the piston reaches the stoppers, the volume

of the cylinder is V$2=188$ liters.

At first, there is $Pl=450$kPa pressure and $ml=6\mathrm{.}183kg$ of water in the

cylinder. A $=0129843kg$ of water is in the vapor phase. Then, heat

transfer occurs until all of the liquid evaporates.

a$)$ Show the phase change of water on the P$-$V diagram. b$)$ Calculate

the pressure and temperature when the piston touches the stoppers, c$)$

final pressure and d$)$ temperature. e$)$ Calculate the work done
