Condensation

Condensation is the change of the physical state of aggregation (or simply state) of matter from gaseous phase into liquid phase. When the transition happens from the gaseous phase into the solid phase directly, bypassing the liquid phase the change is called deposition

Deposition (chemistry)

In chemistry, deposition is the settling of particles or sediment from a solution, suspension and mixture or vapor onto a pre-existing surface....

Sublimation

Sublimation can have several meanings:* Sublimation , the change from solid to gas, while at no point becoming a liquid.* Sublimation , the transformation of emotions....

Condensation commonly occurs when a vapor is cooled to its dew point

Dew point

The dew point is the temperature to which a given parcel of air must be cooled, at constant barometric pressure, for water vapor to Condensation into water....
, but the dewpoint can also be reached through compression.
