How much heat is generated during the complete combustion of 10 kg of dry birch firewood?
| March 10, 2021 | education
The amount of heat released during the complete combustion of 10 kg of dry birch firewood is calculated using the following formula:
Q = q * m, where, according to the condition of the problem, q (specific heat of combustion of dry birch wood) = 8.4 * 10 ^ 6 J / kg, m (mass of dry birch wood) = 10 kg.
Let’s do the calculation:
Q = 8.4 * 10 ^ 6 * 10 = 84 * 10 ^ 6 J = 84 MJ.
Answer: With the complete combustion of birch firewood, 84 MJ of heat will be released.
