How much heat is required to heat a 300 g steel part at 50 degrees?

Formula for calculating the required heat for heating a steel part:

Q = C * m * Δt, where C is the specific heat capacity of steel (tabular value C = 500 J / (K * kg)), m is the mass of the steel part (according to the condition m = 300 g = 0.3 kg), Δt is change in temperature of the steel part (Δt = 50 ° C).

Let’s do the calculation:

Q = 500 * 0.3 * 50 = 7500 J = 7.5 * 10 ^ 3 J = 7.5 kJ.

Answer: 7.5 kJ of heat is required to heat a steel part.
