# Physical & Chemical Properties Changes ## Physical Properties * **State**: * **Color**: * **Odour**: * **Texture**: * **Hardness**: * **Malleability**: Can be bent into shapes * **Ductility**: Can be stretched into a wire * **Brittleness**: Breakability or flexibility of a substance * **Lustre**: Shininess * **Clarity**: * **Viscosity**: Flow ## Chemical Properties * **Corrosive**: Can cause damage by a chemical reaction * **Flammable**: Can burn or ignite easily * **Reactive**: Can change easily when in contact with other substances ## Evidence of Physical Change * Change of state * Blending and mixing * Dissolving * Cutting * Crushing * Change in size and shape * Change in color * Change in odor ## Evidence of Chemical Change * Heat or light is formed * Gas is formed * Precipitate formed (two liquids are mixed and produce a solid) ## Boron (B) ## Bromine (Br) ## Arsenic (As) ## Physical Change A change in which no new substance is made. Usually reversible. ## Chemical Change A reaction that makes a new substance. Not reversible.
