* Physical Change Definition: A physical change alters the form or appearance of a substance but does not change its chemical composition.
* Applying Lipstick: When you apply lipstick, you are simply transferring the lipstick from the tube to your lips. The chemical composition of the lipstick itself does not change. It's still the same lipstick, just in a different location. It can be removed and returned to the original state (the tube).
* Chemical Change Consideration: If it were a chemical change, the lipstick would transform into a new substance entirely. For example, burning the lipstick would be a chemical change.
