The normal freezing point of water is 0.0C. at this temperature the density of liquid water is 1.000 g/ml and the density of ice is 0.917 g/ml. The increase in enthalpy for the melting of ice at this temperature is 6010 J/mol. What is the freezing point of water at 200 atm? Is the freezing point significantly different at 1 bar than it is at 1 atm?
