Physical & Chemical Changes

By Abbey Pruitt

Physical Changes

A physical change is a change in physical properties. For example, ice cream melting is a physical change. Although it is melted, it is still ice cream. It didn't change to a new substance. Another example is tearing paper. Even though it changes in size, it is still paper.

Chemical Changes

A chemical change is any change that results in a new substance. For instance, when metal rusts. The metal turns into a reddish-brown rust (iron oxide). Usually when things change color, they are undergoing a chemical change. Or if something is bubbling, letting off a gas, or catches on fire. Another example is when you burn firewood, the wood turns into ash.
