Prob. $2$: A piston$-$cylinder device with an initial volume of $0\mathrm{.}1m^3,$ as shown in the figure, contains saturated

water vapor at a temperature of $100C.$ The water is compressed so that the final volume is $80\%$ of the

initial volume. If $40$ kJ of heat is lost to the environment through the compression process: Write mass and

energy balance equations, find specific volume at final state, and calculetn$+$hn nintrimal nn$..........$nnlind

$V_1=0\mathrm{.}1m^3$

$T_1=1000C$

$V_2=(0\mathrm{.}1)(0\mathrm{.}8)=0\mathrm{.}88m^3$

$Q_{\text{l}\text{e}\text{s}\text{s}}=40kJ$
