| How much tin can be melted at a swimming temperature, spending 2.95 MJ of the amount of heat (specific heat of floating of a substance = 59 kJ / kg)
Initial data: Q (the amount of heat that was spent on melting tin) = 2.95 MJ (2.95 * 10 ^ 6 J); tin is at its melting point.
Reference values: according to the condition λ (specific heat of fusion of tin) = 59 kJ / kg (59 * 10 ^ 3 J / kg).
The mass of tin that can be melted by spending 2.95 MJ of heat is determined by the formula: m = Q / q.
Calculation: m = 2.95 * 10 ^ 6 / (59 * 10 ^ 3) = 50 kg.
Answer: You can melt 50 kilograms of tin.
