HW#$2-2$ A piston$-$cylinder device initially contains $100L$ of liquid water at $80C$ and $150$kPa.

Find the mass and the total enthalpy of the water

If a pressure $100$ times higher, i$.$e$.,15$MPa, is applied to this device while maintaining the

temperature at $80C,22$ Find the volume and the total enthalpy of the water

Consider the initial state and $\{$:$150$kPa$)$ again, and now we add heat to the water at

constant pressure $(150$ kPa $)$ until the entire liquid is vaporized.

the final temperature and the total enthalpy change, and

show the process on a $T-$v diagram with respect to saturation lines.
