How much heat is released during the complete combustion of 10 kg of coal?
| February 8, 2021 | education
m = 10 kg.
λ = 2.7 * 10 ^ 7 J / kg.
Q -?
The amount of heat Q that is released during the combustion of fuel is determined by the formula: Q = λ * m, where λ is the specific heat of combustion of coal, m is the mass of coal that has burned.
Q = 2.7 * 10 ^ 7 J / kg * 10 kg = 27 * 10 ^ 7 J.
Answer: when coal is burned, Q = 27 * 10 ^ 7 J of thermal energy is released.
