A physical change means that only the appearance of the substance has changed. So if your tear up a piece of paper, its still paper so a physical change has taken place. If you heat or freeze water its only a change of state so its still a physical change. So long as the molecular or chemical structure of the atom/substance does not change it will always be a chemical change. H20 will always be H20.
