Question

The ability of skate blades to travel over ice with very low friction has been suggested to be due to the pressure induced melting of ice, arising from the fact that the density of ice (0.9168 g/cm³) is lower than that of liquid water (0.9998 g/cm³). Using that ?Hfus=6.02 kJ/mol, and assuming that a typical skate will exert a pressure of 300 bar on the surface of the ice, determine the melting temperature of the ice at this pressure. What does this say about the suggestion that pressure induced melting of ice enables skating?
