A steel drill with a mass of 100 g heated up from 15 to 115 degrees Celsius during operation. How much energy was released during heating?
Task data: m (weight of the steel drill taken) = 100 g (0.1 kg); t0 (drill temperature before starting work) = 15 ºС; t (final temperature) = 115 ºС.
Reference values: Cc (specific heat of carbon steel) = 468 J / (kg * K).
The thermal energy that the steel drill will absorb during operation is determined by the formula: Q = Cc * m * (t – t0).
Calculation: Q = 468 * 0.1 * (115 – 15) = 4680 J.
Answer: During operation, the drill will absorb 4680 J of thermal energy.
