The ice at an ice skating rink has a temperature of -5C (268.15 K). Use the Clapeyron equation to calculate the pressure (in atm) that an ice skate blade must exert to permit smooth skating. At 1.00 atm (1.013 x10^5 Pa), ice melts at 273.15 K. The density of ice is 920 kg/m^3, the density of liquid water is 997 kg/m^3 at 273.15. The enthalpy of fusion of water is 333.4 kJ/kg. If you carry out your calculation using SI units your answer will be in pascals.
