# A steel drill with a mass of 10 g heated up during operation from 15 to 115C how much energy was

A steel drill with a mass of 10 g heated up during operation from 15 to 115C how much energy was consumed by the engine unproductively for heating the drill.

To find the indirect energy costs when processing a steel drill taken, we apply the formula: Q = Cc * m * (t2 – t1).

Variables and constants: Cc – specific heat capacity of steel (Cc = 500 J / (kg * K)); m is the mass of the drill (m = 10 g = 1 * 10-3 kg); t2 – final temperature (t2 = 115 ºС); t1 – temperature before treatment (t1 = 15 ºС).

Calculation: Q = Cc * m * (t2 – t1) = 500 * 10 * 10-3 * (115 – 15) = 500 J.

Answer: The indirect energy consumption when processing the taken drill is 500 J.
