Final answer:
Solubility is NOT a physical property of a substance.
Step-by-step explanation:
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. In this case, the physical property of matter is solubility. Solubility refers to the ability of a substance to dissolve in a solvent. It is a characteristic that can be observed without altering the substance's chemical composition.
