What amount of heat will a brick kiln weighing 2 tons transfer to surrounding bodies when it is cooled from 40 degrees to 15 degrees?

The amount of heat that the brick oven will transfer to the surrounding bodies is determined by the formula:

Q = C * m * (tк – tн), where C is the specific heat capacity of a brick (tabular value C = 880 J / (K * kg)), m is the mass of a brick kiln (by the condition m = 2 t = 2000 kg), tк – the initial temperature of the furnace (tк = 40 ºС), tн – the initial temperature of the furnace (tн = 15 ºС).

Let’s calculate:

Q = 880 * 2000 * (40 – 15) = 880 * 2000 * 25 = 44,000,000 J = 44 MJ.

Answer: A brick oven will transfer 44 MJ of heat to the surrounding bodies.
