How much heat will be released during the complete combustion of dry pine wood, if their volume is 0.2.

These tasks: V (volume of burnt dry aspen wood) = 0.2 m3.

Constants: ρ (density of dry aspen) = 510 kg / m3; q (specific heat of combustion of dry aspen wood) = 1.3 * 10 ^ 7 J / kg.

The heat released during the complete combustion of 0.2 m3 of dry aspen firewood is calculated by the formula: Q = q * m = q * ρ * V.

Let’s calculate: Q = 1.3 * 10 ^ 7 * 510 * 0.2 = 1.326 * 10 ^ 9 J = 1.326 GJ.

Answer: With the complete combustion of 0.2 m3 of dry aspen firewood, 1.326 GJ of heat will be released.
