Problem $3$: $(10$ marks$)$

A piston$-$cylinder device initially contains $3$ liters of water at $68F$ and $150$ kPa $.$ Heat is transferred to the

water at constant pressure until half of the mass of water is vaporized.

$($a$)$ what is the final temperature in $C?($b$)$ what is the mass of the water? $($c$)$ determine the total volume

change in $m^3.($d$)$ determine the total enthalpy change in kJ$.($e$)$ show the process on T$-$v$,$ P$-$v$,$ and P$-$T

diagrams with respect to saturation lines.
