.Evaporation is a physical change.

Yes, evaporation is indeed a physical change. Here's why:

1. Definition: Physical changes are changes affecting the form of a chemical substance, but not its chemical composition.

2. Evaporation process: Evaporation is a process where water changes from its liquid state to a gaseous state, also known as water vapor.

3. No new substance formed: During evaporation, the substance (water) doesn't change into a new substance. It just changes its state from liquid to gas. The chemical composition of water remains the same (H2O) before and after evaporation.

4. Reversible process: Evaporation is a reversible process. The water vapor can be cooled down to change it back to its liquid state. This is another characteristic of a physical change.

So, based on these points, we can conclude that evaporation is a physical change.
