Steam $(x=0\mathrm{.}9)$ is enclosed in yet another piston$-$cylinder assembly, at a pressure of $2$MPa.

The system is heated isobarically to a final temperature of $350C.$

a$.(+2$ points$)$ Draw the process on both a T$-$v and P$-$v diagram.

b$.$ points$)$ Calculate the specific work $(k\frac{J}{k}g)$ done by the steam during this

process.

c$.(+3$ points$)$ Calculate the change in specific internal energy of the system. Comment

on if the sign $(+$ or $-)$ makes sense conceptually.

d$.(+3$ points$)$ How much heat was supplied to the system? Comment on if the sign $(+$

or $-)$ of your answer makes sense conceptually.

e$.(+2$ points$)$ How much latent heat $($e$.$g$.,$ specific enthalpy$)$ must be applied to the

steam in order to fully evaporate the water? $($Hint: Use enthalpy and the latent heat

of evaporation$).$
