$,9\mathrm{.}5($a$)$ Use Table II of the Steam Tables to find the mass, the enthalpy and the internal. energy of a system comprising $0\mathrm{.}1m^3$ of wet steam at a temperature $160C$ and a dryness fraction of $0\mathrm{.}94.$

Ans: $0\mathrm{.}3399kg,908\mathrm{.}02kJ,850\mathrm{.}19kJ$

$($d$)$ The system undergoes a fully$-$resisted process at constant pressure to a temperature of $250C.$ During the process there are work and heat interactions between the system and its surroundings. Show the path of this process on a sketch of the $pv$ diagram and evaluate the increase in enthalpy, the increase in internal energy, the work done and the heat transfer.
