This should be in science but....
A chemical change is when two substances combine to make a new substance.
Example: When a car rust, when something gets moldy, or when fire wood starts to burn.
A physical changes is when a substance is changed but it CAN still go back to the form it was previously in.
Example: When ice melts, when cutting wood or paper.
