The heat of fusion fus H for the ice-water phase transition is 335 kJ/kg at 0C

The heat of fusion Δ_fusĤ for the ice-water phase transition is 335 kJ/kg at 0°C and 1 bar. The density of water is 1000 kg/m³ at these conditions, and that of ice is 915 kg/m³. Develop an expression for the change of the melting temperature of ice with pressure.

b. The heat of vaporization for the steam-water phase transition is 2255 kJ/kg at 100°C and 1 bar. Develop an expression for the change in the boiling temperature of water with pressure. 

c. Compute the freezing and boiling points of water in Denver, Colorado, where the mean atmospheric pressure is 84.6 kPa.
