Any characteristic that can be measured, such as an object's density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more, are considered properties of matter.
All matter has certain properties that define it. There are six major physical properties. In order for us to measure or observe them, we do not need to change the composition of the substance. The six physical properties are color, density, volume, mass, boiling point, and melting point.
