How much heat is needed to heat from 0 to 1120 a copper piece weighing 50 kg?

The amount of heat is calculated by the formula:
Q = C * m * (tc – tn), where C is the specific heat capacity of copper (C = 385 J / (K * kg)), m is the mass of the copper part (m = 50 kg), tc is the final temperature of the copper part ( tк = 1120 ºС), tн – the initial temperature of the copper part (tн = 0).
Then:
Q = C * m * (tк – tн) = 385 * 50 * (1120-0) = 385 * 50 * 1120 = 21,560,000 J = 21.56 MJ.
Answer. To heat a copper piece, 21.56 MJ of heat is required.
