Physical Change vs. Chemical Change

The difference between a physical and chemical change is that when a physical change occurs, the substance is the same it is just it looks different. When a chemical change occurs, the entire substance changes, like paper burning. All that is left of the paper is ashes. Ashes are a completely different substance than a match or fire.
