WebPhysical changes are when just the structure of the matter changes, but not the chemicals. Chemical changes are when the identity of the chemicals change where we get new chemical with different properties. Reversibility is not a distinction between the two since there are chemical changes which are reversible and nonreversible. Hope that helps.
