Withn the aid of Clausius Clapeyron and phase diagram Pressure versus Temperature calculate the pressure of water at tempekrature $50$ degrees celcius. Given that specific enthalpy of vaporisation is $2\mathrm{.}26$ x ${10}^{6}kJ$ per $kg$

and the specific volume changes from $1\mathrm{.}673$ cubic metrer per $kgto0\mathrm{.}00104$ cubic metres per $kg.$ Determine the degree $of$ freedom $of$ the change $of$ state $of$ the above process hence state the parameters which can vary whilst mantaining the physical state $of$ this water.
