Compare and Contrast
Chemical Change: It changes the substance by making a new one. In this process it is not reversible and energy can be released or absorbed. This includes a chemical reaction to take place.
Physical Change: Only Changes the appearance but not the chemical component. Dissolving, breaking and melting is included, but this change is easily reversible. This can affect the shape, color, and size.
Both: They both invlove changes in the state of matter. They both have energy changes. There are new things made either way, no matter if the chemical composition is changed or not.
