3. Chemical and Physical Changes

4. Chemical Change – change that results in the production of another (new) substance Signs of Chemical Changes  Color change  Bubbles (formation of gas)  Temperature change  Precipitate (formation of solid)  Change in odor

5. Physical Change – change that does not result in the production of a new substance, a change in the size, shape or state of matter Some physical changes can be reversed. For example, you can refreeze water into ice, but you cannot put your hair back together if you don’t like the cut.
