Silver weight 2 kg. how much heat will be released during its crystallization if silver is at its melting point? Specific heat of fusion of silver 88kJ / kg
Initial data: m (weight of silver) = 2 kg; taken silver was at the melting point.
Reference data: according to the condition λ (specific heat of fusion of silver) = 88 kJ / kg (88 * 10 ^ 3 J / kg).
The amount of heat that will be released during the crystallization of 2 kg of silver is calculated by the formula: Q = λ * m.
Calculation: Q = 88 * 10 ^ 3 * 2 = 176 * 10 ^ 3 J (176 kJ).
Answer: When 2 kg of silver crystallizes, 176 kJ of heat will be released.
