An aluminum container of mass 100 g contains 200 g of ice at −20∘C. Heat is added to the system at a rate of 100 cal s−1. Which of the following represents the variation in the temperature of the system as a function of time? Specific heat capacity of ice = 0.5 cal g−1 ∘C−1, specific heat capacity of aluminum = 0.2 cal g−1∘ C−1 and latent heat of fusion of ice = 80 cal g−1. |
