50 g of ice at a temperature of 0°C is enclosed in a heat-proof shell and subjected to a pressure of 600 atm. How much ice melted if, with an increase in pressure by 138 atm, the melting point of ice decreases by 1 K? Consider the decrease in melting temperature to be proportional to the increase in pressure. The heat capacity and heat of fusion are considered the same as at normal pressure: R = 3.34 105 J/kg, Cl = 2.1 • 103 J/kg deg.
