Define the specific latent heat of fusion of a substance.
Small pieces of ice at 0 ∘C0\text{ }^\circ\text{C}0 ∘C are added to 0.40 kg0.40\text{ kg}0.40 kg of water. The initial temperature of the water is 25.0 ∘C25.0\text{ }^\circ\text{C}25.0 ∘C. The temperature of the water decreases to 0 ∘C0\text{ }^\circ\text{C}0 ∘C. The water loses 42 000 J42\,000\text{ J}42000 J of thermal energy as it cools. All of the ice added to the water melts.
The specific latent heat of fusion of ice is 3.3×105 J/kg3.3 \times 10^5\text{ J/kg}3.3×105 J/kg.
Calculate:
(i) the specific heat capacity of water.
(ii) the mass of ice added to the water.
