An ice skate stands on a blade with a contact surface of 0.0193 cm2 with the ice a) calculate the pressure exerted on the ice by a person with a mass of 67.95 kg and b) which is the melting temperature of ice under this pressure? Data: ΔfusH = 1.4363 Kcal/mol; Tfus= 273.2 K (at p = 1 atm); ice density = 0.92 g/cm3; liquid water density = 1.00 g/cm3 and 1 kg / s2cm = 9.8776 10-4 atm.
