By Anne Marie Helmenstine, Ph.D. Chemical Change Definition: A chemical change is a process where one or more substances are altered into one or more new and different substances. Also Known As: chemical reaction.
A chemical change makes a substance that wasn't there before. There may be clues that a chemical reaction took places, such as light, heat, color change, gas production, odor, or sound. The starting and ending materials of a physical change are the same, even though they may look different.
