Data: m1 (weight of silver) = 1 kg; m2 (paraffin mass) = 1 kg.
Reference values: λ1 (specific heat of crystallization of silver) = 0.87 * 10 ^ 5 J / kg; λ2 (specific heat of crystallization of paraffin) = 1.5 * 10 ^ 5 J / kg.
1) Heat energy during solidification of 1 kg of silver: Q1 = λ1 * m1 = 0.87 * 10 ^ 5 * 1 = 87 kJ.
2) Heat energy during hardening of 1 kg of paraffin: Q2 = λ2 * m2 = 1.5 * 10 ^ 5 * 1 = 150 kJ.
Answer: When 1 kg of silver and 1 kg of paraffin are cured, 87 kJ and 150 kJ of energy will be released, respectively.
