a$.$ Using the saturated liquid model, determine the specific enthalpy, specific volume, and specific internal energy of water at $300$ kPa and $\backslash (100^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ).$

b$.$ Water at $150$ kPa and $\backslash (50^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$ goes through a process that results in a pressure of $1750$ kPa and a temperature of $\backslash (100^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ).$ Using the incompressible substance model, determine the change in specific internal energy, and change in specific enthalpy of the water.
