How much heat will be used to heat a brick measuring 24x12x6.5 cm from 20 to 980 degrees.
| February 16, 2021 | education
Initial data: the dimensions of the brick taken are 24x12x6.5 cm (0.24×0.12×0.065 m); t0 (initial brick temperature) = 20 ºС; t (final temperature) = 980 ºС.
Constants: ρк (density of clinker bricks) ≈ 2000 kg / m3; CK (specific heat of a brick) = 880 J / (kg * K).
The amount of heat that will go to heat the brick is determined by the formula: Q = Cк * m * (t – t0) = Cк * a * b * c * ρк * (t – t0).
Calculation: Q = 880 * 0.24 * 0.12 * 0.065 * 2000 * (980 – 20) ≈ 3.16 * 106 J (3.16 MJ).
