2) Janice is your boss and she has heard that changes in enthalpy with respect to pressure at constant temperature are larger than changes in internal energy changes for condensed

phases. Do the derivations that allow you to find these two changes. Then use the virial equation of state to calculate both quantities for water at 200 °C and ambient pressure and let her know by what amount, in J/mol, the internal energy difference is smaller. Recall that the virial equation can be written as:PT V=\frac{R T}{P}+B
