# Physical & Chemical Properties Changes ## Physical Properties * **State:** * **Color:** * **Odor:** * **Texture:** * **Hardness:** * **Malleability:** (can be bent into a shape) * **Ductility:** (a material can be stretched into a wire) * **Brittleness:** (breakability/flexibility) * **Lustre:** (shininess) * **Clarity:** * **Viscosity:** (flow) ## Chemical Properties * **Corrosive:** can cause damage by chemical reaction * **Flammable:** can burn or ignite easily * **Reactive:** can change easily when in contact with other substances ## Evidence of Physical Changes * **Change of state** * **Blending and mixing** * **Dissolving** * **Cutting** * **Crushing** * **Change in size and shape** ## Evidence of Chemical Changes * **Change in color** * **Change in odor** * **Heat or light is formed** * **Gas is formed** * **Formation of precipitate:** (two liquids are mixed and form a solid) ## Physical Change A change in which no new substance is formed. Usually reversible. ## Chemical Change A reaction that makes a new substance. Not reversible.
