How much heat is needed to heat 1 kg of steel by 2 ° C?

To calculate the required heat for heating the steel taken, we will use the formula: Q = Cc * m * Δt, where Cc is the specific heat capacity of the steel (according to the condition Cc = 500 J / (kg * ºС)); m is the mass of the steel taken (m = 1 kg); Δt is the required temperature change (Δt = 2 ºС).

Let’s perform the calculation: Q = Cc * m * Δt = 500 * 1 * 2 = 1 * 10 ^ 3 J = 1 kJ.

Answer: To heat 1 kg of steel, it will be necessary to spend 1 kJ of heat.
