Water, initially at $90$ Celsius and $200$ kPa, is heated isothermally $($yes$,$ this can happen$$adiabatic and isothermal are not the same things$)$ until it has a specific volume of $1\mathrm{.}5$ m$3/$kg

What regime is the final state $($superheated vapor, saturated mixture, saturated liquid, etc.$)?$

Determine the final pressure

Determine the change in specific internal energy

Draw the process on a P$-$v diagram

Draw the process on a T$-$v diagram
