Student exploration melting points.
Jul 11, 2017 · Melting points also demonstrate a chemical reaction. Not just any change equals a reaction. For example, an air conditioner cooling off the air in a hot room is not causing a chemical reaction. It’s making a physical change. By contrast, in a chemical reaction, molecules interact, resulting in the change. Atoms may bond, and then those bonds ...
