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

univerkov | May 5, 2021 | education

Initial data: m (mass of steel for heating) = 1 kg; Δt (change in steel temperature) = 2 ºС.

Reference values: C (specific heat capacity of steel) = 500 J / (kg * K).

The required amount of heat for heating 1 kg of steel can be calculated by the formula: Q = C * m * Δt.

Let’s calculate: Q = 500 * 1 * 2 = 1000 J or 1 kJ.

Answer: To heat 1 kg of steel at 2 ºС, 1 kJ of heat is required.
