How much heat will be released during the complete combustion of pine firewood weighing 15 kg

Data: m (mass of consumed pine wood) = 15 kg; qsd – beats heat of combustion of dry pine wood (qsd = 12.5 MJ / kg).

The released heat: Q = m * qsd = 15 * 12.5 = 187.5 MJ.

Answer: When 15 kg of pine firewood is burned, 187.5 MJ of heat will be released.
