Some body weighing 1 kg, when heated at 60 degrees, received an amount of heat of 24 kJ

Some body weighing 1 kg, when heated at 60 degrees, received an amount of heat of 24 kJ. What is the specific heat capacity of the substance from which the body is made?

Problem data: m (mass of some body) = 1 kg; Δt (temperature change during heating) = 60 ºС; Q (heat received by the body) = 24 kJ (24 * 10 ^ 3 J).

We express the specific heat capacity of a substance from the formula: Q = Cx * m * Δt, whence Cx = Q / (m * Δt).

Let’s calculate: Cx = 24 * 10 ^ 3 / (1 * 60) = 400 J / (kg * K).

Answer: A certain body was made of a substance with a specific heat of 400 J / (kg * K).
