Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others. The three states of matter are: solid, liquid, and gas. The melting point and boiling point are related to changes of the state of matter. All matter may exist in any of three physical states of matter. In the graphic on the left the solid and liquid forms of water - ice are shown.
In case (b), we have a physical change: warm metal is still metal; the fundamental characteristics of the metal are unaltered. Cases (c) and (d) are also examples of physical changes. Water condenses from the gaseous state to the liquid state on the surface of the metal; water is still a pure substance, whether it is in the liquid or gaseous state, and the metal is unchanged chemically by the condensation. Similarly, in case (d), the carbon which is deposited on the metal is still pure carbon.
