A metal cylinder with a mass of 250g was transferred to 46kJ of heat and it was heated from 25 degrees

A metal cylinder with a mass of 250g was transferred to 46kJ of heat and it was heated from 25 degrees to 225 degrees from what kind of metal the cylinder was made.

Data: m (mass of a metal cylinder) = 250 g; Q (the amount of heat that was transferred to the cylinder) = 46 kJ; t0 (initial cylinder temperature) = 25 ºС; t (final temperature of cylinder heating) = 225 ºС.

SI: m = 250 g = 0.25 kg; Q = 46 kJ = 46 * 10 ^ 3 J.

Let us determine the specific heat capacity of the metal of the cylinder from the following formula: Q = C * m * (t – t0), whence C = Q / (m * (t – t0)).

Calculation: C = 46 * 10 ^ 3 / (0.25 * (225 – 25)) = 920 J / (kg * K).

Answer: The metal cylinder is made of aluminum.
