A piston$-$cylinder device contains $0\mathrm{.}1$ m

$3$

of liquid water and $0\mathrm{.}9$ m$3$

of water vapour in equilibrium at $700$ kPa. Heat is transferred at

constant pressure until the temperature reaches $400$C$.$

a$)$ Show the process in a p$-$v diagram with respect to the saturation

lines.

b$)$ Determine the initial temperature of the water.

c$)$ Determine the mass of the water

d$)$ Calculate the final volume.
