What property of matter can be identified without changing the identity of the substance?
The property of matter that can be identified without changing the identity of the substance is called a physical property. Examples of physical properties include color, smell, freezing point, boiling point, and density. These characteristics can be observed or measured without altering the chemical structure of the substance. In contrast, chemical properties involve changes to the substance's identity during a chemical reaction.
