Q4. (20 marks) A mass of ice at -15.0°C in a very light container receives heat at the constant rate of 800.0 J/min. Specific heat capacity of ice: 2.01 x 10° J.(kg.K)", latent heat of fusion of ice: 3.34 x 10ʻJ/kg. The ice starts to melt after 20.8 minutes. (a) Find the mass of the ice in the container. (b) After how many minutes, from the time when the heating is first started, does the temperature begin to rise above 0.0°C? (c) Plot a diagram showing the change of temperature as a function of the time. Explain clearly each stage of all the process.
