Physical Change is: A change in the physical properties of a substance, not in the substance itself.

Signs of Physical Changes: Change in state or phase Change of shape Change of size

Chemical Changes: Is when a substance changes into a new substance.

Signs of Chemical Changes: Change in color Burning Rusting Bubbles appear as a gas is formed Change in odor Change in temperature Formation of a solid
