2. A block of melting ice with mass 0.02 kg is put into a polystyrene cup containing 0.3 kg of water with initial temperature 20°C. After the mixture is stirred well, the ice block melts completely and the final temperature of the water becomes 14°C. Which of the following equations can be used to find the specific latent heat of fusion of ice, L ? (Given: Specific heat capacity of water = 4200 J kg ¹C¹) A. 0.3 × 4200 × 6 = 0.02 L B. 0.3 x 4200 × 6 = 0.02 L - 0.02 x 4200 × 6 C. 0.3 × 4200 × 6 = 0.02 L + 0.02 x 4200 × 6 D. 0.3 x 4200 × 6 = 0.02 L + 0.02 x 4200 × 14 ​
