WebAug 2, 2024 · Summary. 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. A chemical property describes the ability of a substance to undergo a specific chemical change. WebPhysical property. A physical property is any property that is measurable, whose value describes a state of a physical system. [1] The changes in the physical properties of a system can be used to describe its changes between momentary states. Physical properties are often referred to as observables.
