What changes in a chemical change that does not change in a physical change?

In: Chemistry [Edit categories]

Answer:

If you bend a paper clip it is a physical change because it is still a paper clip. It's chemical identity has not changed. In a chemical change, the chemical identity of a substance changes. For example, if the paper clip were made of steel and rusted, then it's chemical identity would change to include oxygen chemically bonded to the metal, iron oxide.
