How much heat will be released when 100 kg of molten tin solidifies?

Since further cooling of tin is not specified, we calculate only the heat of crystallization of tin using the following formula:

Q = λ * m, where λ is the specific heat of fusion, crystallization of tin (tabular value λ = 0.59 * 10 ^ 5 J / kg), m is the mass of tin (according to the condition m = 100 kg).

Let’s do the calculation:

Q = λ * m = 0.59 * 10 ^ 5 * 100 = 0.59 * 107 = 5.9 * 10 ^ 6 J = 5.9 MJ.

Answer: When 100 kg of molten tin solidifies, 5.9 MJ of heat will be released.
