What happens to wood after being burned?

It may seem as though burning destroys matter, but the same amount, or mass, of matter still exists after burning wood as before.

The Law of Conservation of Mass states that matter cannot be created or destroyed, so the weight of the matter is the same. Also suppose you had been able to measure the oxygen used by the fire and the gases produced by the fire. What would you find? The total mass of matter after the fire would be the same as the total mass of matter before the fire.

When wood burns, it combines with oxygen and changes not only to ashes but also to carbon dioxide and watervapor. The gases float off into the air, leaving behind just the ashes.
