| physical property | Examples include color & odor |
| physical change | When this occurs, the material remains the same, even though its form appears to have changed. |
| chemical property | Examples include permanent color change & rust formation |
| chemical change | A permanent change; the original substance changes into a new substance |
| combustion | Burning |
