Exercise 1

The enthalpy change (heat of fusion, H f ) for the transition ice water at 0 °C and 1 atm pressure is +6.01 kJ/mol. The change in volume when 1 mole of ice is melted is 1.625 cm 3 /mol = 1.625 × 10 6 m 3 /mol. Calculate the difference between H f and A U f for this process, and express it as a percentage of H f. [Note: 1 atm = 1.013 × 10 5 N/m 2 in SI units, where N = newton.]
