Determine how much heat is given to the room by a stove consisting of 150 bricks

Determine how much heat is given to the room by a stove consisting of 150 bricks, weighing 3.6 kg each, if its temperature decreases from 65 to 15 C.

Data: n (number of bricks) = 150 pieces; m1 (mass of one brick) = 3.6 kg; t1 (initial temperature of bricks) = 65 ºС; t2 (end temperature) = 15 ° C.

Constants: CK (specific heat capacity of a brick) = 880 J / (kg * K).

To determine the amount of heat given off by a brick oven, we use the formula: Q = CK * m * (t1 – t2) = CK * n * m1 * (t1 – t2).

Let’s perform the calculation: Q = 880 * 150 * 3.6 * (65 – 15) = 23.76 * 10 ^ 6 J (23.76 MJ).

Answer: A brick oven will transfer 23.76 MJ of heat to the room.
