One mole of ice is warmed from 220 K to 300 k at constant pressure of 1 bar. Find the enthalpy change for this process 2) If we assume that the volume of the ice/water does not change significantly during the process in #1 what is the energy change? 3) When the ice melts the density change from .9167 g/cm^3 to 1.000 g/cm^3. If we assume that the volume change is due entirely to this density change (that is we neglect thermal expansion of the ice/water), what is the difference between the enthalpy change and the energy change during theis process? Is this a significant difference, compared to the total energy
