A calorimeter with a heat capacity C = 600 J/deg contains m = 1 kg of ice. What amount of heat Q1 and Q2 must be supplied to the calorimeter with ice in order to heat it by 2 degrees: a) from temperature T1 = 270 K to T2 = 272 K; b) from temperature T1 = 272 K to temperature T2 = 274 K? The specific heat capacity of water cw = 4.2 kJ/kg deg, and of ice cw = 2.1 kJ/kg deg. Specific heat of melting of ice L = 330 kJ/kg.
