Explanation:

Matter is defined as the substance that has mass and occupies space. So basically a physical property of a substance helps us to determine whether a substance is matter or not.

As a property that does not bring any change in chemical composition of a substance are known as physical properties.

For example, shape, size, mass, volume, density, etc of a substance are all physical properties.

Thus, we can conclude that the defining characteristics of matter are physical properties.
