During the crystallization of water at a temperature of 0 degrees Celsius, 34 kJ of heat is released. Determine the mass of ice formed?
Given: Q (amount of heat released during crystallization) = 34 kJ (34 * 10 ^ 3 J); the water before turning into ice was at the crystallization temperature (0 ºС).
Reference data: λ (specific heat of crystallization of water) = 3.4 * 10 ^ 5 J.
The mass of the formed ice is equal to the ratio of the released heat and the specific heat of crystallization: m = Q / λ.
Calculation: m = 34 * 10 ^ 3 / (3.4 * 10 ^ 5) = 0.1 kg (100 g).
Answer: The mass of the formed ice is 100 grams.
