As the gas escapes, the fire will emit an audible pop or crack. This same principle rings true when burning wet or moist firewood. Unlike wood, water doesn’t convert into heat when burned.
Gas is created by trapped moisture locked in small pockets within the wood. Some will get stuck in the wood. In basic terms, it has something to do with the combustion gases escaping from the wood.
Trapped moisture can also cause wood to pop and crackle from the creation of steam. As the wood burns the moisture is heated, and as the moisture is heated it expands and turns into gas. If you place a pot of water on the stove and activate the burner, it will evaporate as steam.
See answer (1) best answer. The holes created by the insects will give the gasses an escape route. All trees need to take in water to survive.
