Fig. 3 T(°C) Х 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 103 J.(kg.K)-1. (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. 100 80 60 40 20 0 t(min) 25 100 200 300 400 500 Fig. 4
