Answer:
When temperature increases, cellulose starts to pyrolyse. The decomposition products either remain inside the material or are released as gases. Gaseous substances react with each other and oxygen, releasing a large amount of heat that further induces pyrolysis and combustion reactions.

Answer:
It shows that when wood burns, it combines with oxygen and changes not only to ashes, but also to carbon dioxide and water vapor.
The gases float off into the air, leaving behind just the ashes.
Suppose you had measured the mass of the wood before it burned and the mass of the ashes after it burned
