Determine how much heat is required to melt 200 g of tin at 232 ° C.

Initial data: m (mass of tin for melting) = 200 g = 0.2 kg; t (tin temperature) = 232 ºС (corresponds to the melting point).

Constants: λ (specific heat of fusion of tin) = 0.59 * 105 J / kg.

The required amount of heat for melting 200 grams of tin is calculated by the formula:

Q = λ * m.

Let’s perform the calculation:

Q = 0.59 * 105 * 0.2 = 11800 J or 11.8 kJ.

Answer: To melt 200 grams of tin, 11.8 kJ of heat is required.
