5) Calculate the total heat energy removed during making of 1.5 kg ice cream. The initial temperature of the ice cream mixture is 24 °C and the final temperature of the ice cream produced is -6 °C. The freezing temperature, Tf, of the ice cream mixture is -3 °C. The ice cream mixture has 67% water. The specific heats of ice cream mixture and ice cream are 3.3 kJ/kg °C and 1.88 kJ/kg °C, respectively. Enthalpy of ice melting is 334 kJ/kg.
