* Physical Change: A physical change alters the form or appearance of a substance but does not change its chemical composition.
* Melting copper simply changes its state from solid to liquid. The copper atoms themselves remain the same.
* Chemical Change: A chemical change results in the formation of new substances with different chemical properties.
* For example, burning copper would be a chemical change because it would react with oxygen to form copper oxide, a new substance with different properties.
In summary: Melting copper is a physical change because the copper atoms remain the same, just in a different state of matter.
