| February 19, 2021 | education
The required amount of heat to heat 5 kg of steel:
Q = С * m * Δt, where С is the specific heat capacity of steel (С = 500 J / (kg * K)), m is the mass of steel (m = 5 kg), Δt is the change in steel temperature (Δt = 2 ºС).
Q = C * m * Δt = 500 * 5 * 2 = 5000 J = 5 kJ.
Answer: To heat 5 kg of steel at 2 ºС, 5 kJ of heat is needed.
