A close piston$-$cylinder device contains $24$ g of saturated water vapor that is maintained at a constant pressure of $300$ kPa. A resistance heater within the cylinder is turned on and passes a current of $0\mathrm{.}2$ A for $5$ min from a $120-$V source. At the same time, aheat loss of $11$ kj occurs. Determine the the final internal energy in kj$/$kg if you know that final volume the system is $1\mathrm{.}34139$ m$3/$kg
