A chemical change cant be undone and a new substance, so in other words you cant reverse the effects and in the end you get ashes. An example of a chemical change would be burning paper and getting ashes. A physical change can be undone. An example of a physical change would be bending the paper because you can still get the paper back and no new substance is created.
