How much heat is required to heat 10,000 g steel by 20 degrees?

To estimate the cost of heat for heating the steel taken, we use the formula: Qx = Cst * m * Δt, where Cst – beats. heat capacity of carbon steel (const, Cst = 468 J / (kg * K)); m is the mass of the steel taken (m = 10,000 g; in the SI system m = 10 kg); Δt – considered temperature change (Δt = 20 ºС).

Let’s perform the calculation: Qx = Cst * m * Δt = 468 * 10 * 20 = 93.6 * 10 ^ 3 J.

Answer: To heat 10,000 g of steel, 93.6 kJ of heat is required.
