A side-by-side comparison to physical change makes the matter crystal clear. Chemical changes are also known as chemical reactions. The other kind of change in chemistry is a physical change, which is when a substance changes without becoming a new chemical. Grinding, melting, dissolving, and evaporating are all physical changes. A . A chemical change is a change in the composition of the original substance. When a chemical change occurs, something new is formed. The main purpose of the experiment is of course to introduce physical and chemical change, and the associated ideas of reversible and non-reversible changes. A chemical change, also known as a chemical reaction, is a process in which one or more substances are altered into one or more new and different substances. Chemical changes are frequently harder to reverse than physical changes. As a result of a chemical reaction, new substances with new properties are formed.
