Condensation Definition in Chemistry

What Condensation Means in Chemistry

close up on condensation on glass

Condensation is the change in the state of matter from the gas phase to the liquid phase. It is the reverse of vaporization.

During condensation, atoms and molecules form clusters. For example, within a cloud, water nucleates around a dust, pollen, or microbial particle. Eventually the clusters reach sufficient mass to form droplets.
