Question

The basic principle of calorimetry is as follows: Heat gained by one body = Heat lost by other body. This statement follows from the law of conservation of energy. An aluminium container of mass 100 g contains 200 g of ice at 20 C. Heat is added to the system at the rate of 420 J s1. Specific heat capacity of ice = 2100 J kg1 K1, specific heat capacity of aluminium = 840 J kg1 K1 and latent heat of fusion of ice = 3.36  105 J kg1. 39. The time required to raise the temperature of the container and ice from 20 C to 0 C is ​
