A physical change only changes the appearance of an object, it's chemical makeup is still the same. Melting ice doesn't change it to a different object, just a different state. Like if you rip a piece of paper, it's still a piece of paper. But a chemical change changes the makeup of the object. Burning is a chemical change. Once it burns it is no longer paper.
