A piston$-$cylinder device initially contains $1\mathrm{.}4$ kg of saturated liquid water at

$200C.$ Now, heat is transferred to the water under constant pressure until the

temperature reached $250C.$

a$.$ Determine the change in volume.

c$.$ Calculate the change in the internal energy, in kJ$.$

d$.$ Construct the $P-v$ and $T-v$ diagram of the process.
