No, the condensation of water vapor is not a chemical reaction. It is a physical change. Here's why:

* Chemical Reactions: Involve the formation of new substances with different chemical compositions. Atoms are rearranged to form new bonds.

* Physical Changes: Involve a change in the physical state of a substance, but not its chemical composition.

Condensation is simply the process of water vapor (gaseous state) changing into liquid water (liquid state). The chemical formula of water (H₂O) remains the same.
