Small drops of water that accumulate on surfaces colder than the surrounding air, such as on cold drinking glasses. 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 windows and 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
• fog / mist
• steam
• wet lens
