How much heat will be released during the complete combustion of 500 grams of firewood?
| May 11, 2021 | education
The amount of heat that will be released during the complete combustion of 500 grams of firewood is calculated using the following formula:
Q = q * m, where q is the specific heat of combustion of dry firewood (for dry firewood we take q = 1 * 10 ^ 7 J / kg), m is the given mass of firewood (m = 500 g = 0.5 kg).
Let’s calculate the released heat:
Q = q * m = 1 * 10 ^ 7 * 0.5 = 5 * 10 ^ 6 J = 5 MJ.
Answer: With the complete combustion of 500 grams of firewood, 5 MJ of heat will be released.
