Quizplus · Accepted Answer

When wood is burned, it undergoes a chemical reaction whereby it combines with oxygen from the air to form gaseous compounds such as carbon dioxide and water vapor, which are released into the atmosphere. This means that the mass of the wood is not conserved, as some of it is converted into gases that escape into the environment.
