Under atmospheric pressure, water freezes at 0 °C. The latent heat of fusion is 6.01 × 103 J/mole. At the melting point, the density of ice is 0.917 g/cm3, and that of liquid water is 0.9999 g/cm3. The molecular weight of water is 18.
(a) What are the molar volumes (in m3) for water in the solid and liquid phases at the melting point?
(b) What is the change in molar volume of the water when the solid is melted?

(c) To force water to melt at a lower temperature, would the pressure on it have to increase or decrease?
