Burning wood is an example of a chemical change. In this process, the wood undergoes a reaction with oxygen, resulting in the formation of new substances such as ash, smoke, and gases. The other options—stretching a rubber band, folding paper, and chopping vegetables—are examples of physical changes, where the substances involved do not change their chemical composition.
