| June 28, 2021 | education
Tasks: m (mass of hardening tin) = 200 g; Tin was at crystallization temperature.
Reference values: λ (specific heat of tin crystallization) = 0.59 * 10 ^ 5 j / kg.
The highlighted heat during clarification of 200 g of tin is determined by the formula: Q = λ * m.
Calculation: Q = 0.59 * 10 ^ 5 * 0.2 = 11 800 J (11.8 kJ).
Answer: When curing 200 g of tin, 11.8 kJ warmth was released.
