When increasing pressure from 1 atm to 2 atm, calculate the magnitude of the change in freezing point for water (Hfusion = 6.009 kJ/mol) and the density of ice is 0.9167 g/cm3 while that for liquid water is 0.9999 g/cm3 (the normal melting point for water is 0 at 1 atm). (molecular weight of water is 18.016 g/mol)
