Q4. (20 marks) An open container holds a mass of ice at -15.0°C. The mass of the container can be ignored. Heat is supplied to the container at the constant rate of 800.0 J/min for 500.0 min. Specific heat capacity of ice: 2.01 x 10° J.(kg.K)! (a) Explain the phase change of the ice based on the curve showing the temperature change as a function of the elapsed time in Fig. 4. (b) Find the mass of the ice in the container and the latent heat of fusion of ice. Fig. 3 7(°C) 100 80 60 40 20 0 25 100 200 300 400 500 (min) Fig. 4
