How do you classify a change in a substance as physical or chemical? A physical change: * can be observed; * is reversible; * takes place when the form (state) of the substance changes without changing its chemical composition (the change does not affect the structure). A chemical change (reactions): * appears when one substance is transformed into another substance (which then becomes a new set of properties‚ thus a new substance); * can be observed (via change in color‚ smell
