* Physical properties are characteristics of a substance that can be observed or measured without changing the substance's chemical composition.

* Chemical properties describe how a substance reacts with other substances or how it changes its chemical composition.

The state of matter (solid, liquid, gas) is determined by the arrangement and movement of molecules within the substance. It doesn't involve changing the substance's chemical makeup.

Here are some other examples of physical properties:

* Color

* Density

* Melting point

* Boiling point

* Hardness
