Growing of a piglet into a pig

Growth of a "piglet into pig" is a chemical change. Explanation: This is because, this process of growth of a piglet into a pig is an irreversible change, which means, once the piglet has grown, nothing can be done to remove the change and make the pig turn into its smaller form, a piglet again.
