m = 15 kg.
λ = 3.4 * 10 ^ 7 J / kg.
Q -?
The amount of heat Q that is released during the combustion of a substance is determined by the formula: Q = λ * m, where λ is the specific heat of combustion of the fuel, m is the mass of the substance that has burned.
Q = 3.4 * 10 ^ 7 J / kg * 15 kg = 51 * 10 ^ 7 J.
Answer: when burning 15 kg of charcoal, Q = 51 * 10 ^ 7 J of thermal energy was released.
