| May 25, 2021 | education
Initial data: m (mass of completely burnt dry wood) = 10 kg.
Constants: q (specific heat of combustion of dry wood) = 10 MJ / kg = 10 * 10 ^ 6 J / kg.
We find the amount of heat using the following formula: Q = q * m.
Calculation: Q = 10 * 10 ^ 6 * 10 = 100 * 10 ^ 6 J or 100 MJ.
Answer: With the complete combustion of 10 kg of dry wood, 100 MJ of heat will be released.
