Knowing that for water (18.015 g/mol) at 0 C and 1 bar the enthalpy of fusion is 6006.78 J/mol, the density of ice is 0.9168 g/mL and that of liquid water is 0.9998 g/mL, calculate what would be the pressure required for the melting temperature to be reduced to -3 C. Assume that the enthalpy of fusion and the volumes of the solid and liquid phases are constant over the temperature and pressure range. Return the result in (bar).
