Heat. The warm water returned to nearby ecosystems can cause stress for local species. The composition of steam will be the same in both liquid and vapours form. A chemical change results in the formation of one or more new substances: For example, When we burn a piece of paper with a lit match stick, then entirely new substances such as carbon dioxide, water vapour, smoke, and ash are produced. Any chemical reaction involves two categories of chemicals products and reactants. Products are the chemicals created by the reaction, while reactants are the chemicals that interact, combine, or break down to make the product.
