A calorimeter of mass 60 g contains 180 g of water at 29°C. Calculate the common final equilibrium temperature of the mixture if 37.2 g of ice at - 10°C is added to it. Specific
heats are given as follows: ice = 2108 J/kg. K, calorimeter = 0.42 J/g.°C, water =
4186J/kg.°C and latent heat of fusion for ice is 333 kJ/kg.
