Small drops of [[water]] that accumulate on surfaces colder than the surrounding air, such as on cold [[drinking_glass|drinking glasses]]. [[dew drop|Dew]] is a form of condensation usually found mornings after objects drop in temperature overnight. In freezing temperatures, condensation may take the form of [[frost]].

Condensation on glass surfaces such as [[window|windows]] and [[mirror|mirrors]] may produce a [[window fog]] effect (post #1579162). See the [[glass writing]] tag for text and symbols made on fogged glass with one's finger. 

Please don't confuse the appearance of condensation on glass with [[frosted glass]], where the glass itself is created to have a foggy appearance.

Contrast the condensation found on solid objects with various types of airborne water droplets:

* [[breath]]
* [[cloud]]
* [[contrail|contrail]]
* [[fog]] / mist
* [[steam]]
