An ice skate is able to glide over the ice because the skate blade exerts sufficient pressure on the ice that a thin layer of ice is melted. The skate blade then glides over this thin melted water layer. Determine the pressure an ice skate blade must exert to allow smooth ice skate at -10C. The following data is given for the range of temperatures and pressures involved. hfg(ice) -334 kJ/kg: Vliq. 1x 10 m'kg; Vice- 1.01 103 m/kg. The initial conditions are P = 1 atm, T-0C. Justify your answer. 2.
