Q4. (20 marks) Heat is supplied at a constant rate to 0.550 kg of ice at -15.0°C in a very light container. Specific heat capacity of ice: 2.01 x 10 J.(kg.K)'. The ice starts to melt after 20.8 minutes. (a) Find the rate of heat received by the ice (in J/minute). (b) Knowing that after 250.8 minutes from the time when the heating is first started, the temperature begin to rise above 0.0°C. What is the latent heat of fusion of ice? (c) Plot a diagram showing the change of temperature as a function of the time. Explain clearly each stage of all the process.
