Explanation:

Physical changes do not alter the chemical composition of a substance, while chemical changes result in the formation of new substances with different chemical properties. When charcoal burns, it reacts with oxygen in the air to produce carbon - dioxide and other by - products. This is a chemical reaction as new substances are formed. The original carbon in the charcoal combines with oxygen to create carbon - dioxide gas. There is a change in the chemical bonds and the identity of the substances involved.

Answer:

Charcoal burning is a chemical change because new substances like carbon - dioxide are formed during the burning process as a result of a chemical reaction with oxygen.
