* Chemical properties describe how a substance reacts or changes its composition. Boiling point is the temperature at which a substance changes from a liquid to a gas. This change involves breaking intermolecular forces, which are related to the substance's chemical structure and bonding.
* Physical properties can be observed without changing the substance's composition. Examples include color, density, and melting point. Boiling point, on the other hand, involves a change in the substance's state of matter.
In summary: Boiling point is a chemical property because it relates to the substance's chemical structure and the strength of the forces holding its molecules together.
