Which term describes the ability of a substance to change into a new substance with different properties?

The ability of a substance to change into a new substance with different properties is known as a chemical property. This term refers specifically to how a substance interacts with other substances, as well as how it undergoes transformations that result in the formation of new substances. Examples of chemical properties include flammability, reactivity with acids, and the ability to oxidize, all of which indicate how a substance may change under certain conditions.

In contrast, physical properties involve characteristics that can be observed or measured without altering the substance's chemical structure, such as color, melting point, and boiling point. Atomic and molecular properties are not standard terms used to describe the change of substances into new forms; rather, they pertain to the structure and behavior of atoms and molecules, respectively.
