2. What is the amount of heat released when 0.8 kg of water at 25°C cools until it becomes ice at -6°C? State the assumptions make in your calculations. [Specific heat capacity of water, Cwater = 4.2 x 103 J kg 1 °C-?, specific heat capacity of ice, Cice = 2.0 x 103 J kg-1 °C -1 and specific latent heat of fusion of ice, le = 3.34 x 105 J kg ']
