To what temperature will a piece of tin with a mass of 10 grams, taken at a temperature of 20 degrees

To what temperature will a piece of tin with a mass of 10 grams, taken at a temperature of 20 degrees Celsius, be heated when 57J of heat is transferred to it from the belt?

Initial data: m (mass of a piece of tin) = 10 g (0.01 kg); t0 (initial tin temperature) = 20 ºС; Q (heat transferred to a piece of tin from a soldering iron) = 57 J.

Reference values: Cо (specific heat of tin) = 230 J / (kg * ºС).

We express the steady-state temperature of a piece of tin from the formula: Q = Co * m * (t – t0), whence t = Q / (Co * m) + t0.

Calculation: t = 57 / (230 * 0.01) + 20 = 44.8 ºС.

Answer: After the transfer of heat from the soldering iron, the piece of tin will heat up to 44.8 ºС.
