Chemical and Physical Changes

Chemical Change is when substances are produced with new chemical properties. When Chemical bonds of a substance are broken and released a new chemical is formed.

Physical Change is when substances change phase or form.

Chemical Change

• Baking soda and vinegar are examples of chemical change. Mixing baking soda and vinegar together causes a chemical reaction.

Physical Change

• Tearing a piece of paper is an example of Physical Change because the tearing of the paper only changes the shape and size of it.
