For example burned wood becomes ash carbon dioxide and water. Rotting burning cooking and rusting are all further types of chemical changes because they produce substances that are entirely new chemical compounds. What are chemical changes give two examples?

You can prove that this is a physical change because if you put the melted butter back in the fridge it changes back to solid butter. When you first apply heat to a solid substance like butter it melts into a liquid.
