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

Module One: Grade Nine Topics Physical Change: This is a usually reversible change in which the form of matter is altered‚ but is not chemically changed to another substance. Melting an ice cube is an example of a physical change. The ice cube changes states: from a solid to a liquid (water). You can physically see this change. No new substance is formed: the matter in the liquid is the same as it was in the ice cube. It is reversible: you can freeze the liquid to turn it back to ice.
