Condensation
kon-den-SAY-shun
/ˌkɒndɛnˈseɪʃən/
The process by which water vapor in the air changes into liquid water, forming clouds, fog, or dew.
It's the opposite of evaporation and is crucial for cloud formation and precipitation.
The story behind the word. The word 'condensation' comes from the Latin prefix 'con-', meaning 'together', and the verb 'densare', meaning 'to make thick' or 'to make dense'. So, it literally means 'to make dense together'. This describes how dispersed water vapor molecules come 'together' and become 'dense' enough to form liquid droplets.
Word relationships
- liquefaction: More general, can refer to any gas turning into liquid, often under pressure, not just water vapor in air.
- evaporation: The opposite process, where liquid changes into gas.
Commonly confused with
- Evaporation: Evaporation is liquid to gas; condensation is gas to liquid.
Word family
- condense (verb): To change from a gas or vapor to a liquid; to make something more dense or concentrated.
- condenser (noun): A device or apparatus for condensing vapor or gas.
Collocations
- water condensation
- condensation nuclei
- surface condensation
- atmospheric condensation
Example sentences
- "As warm, moist air rises and cools, the water vapor undergoes condensation, forming tiny cloud droplets." Explaining cloud formation.
- "The cold glass of iced tea quickly developed condensation on its exterior surface in the humid room." A common household observation.
Memory hook
Think of 'CON-DENSE-ATION' as molecules coming 'CON' (together) to become 'DENSE' and form liquid. Come together, get dense
When not to use
Do not use 'condensation' to refer to the process of freezing (liquid to solid); it specifically refers to gas to liquid.
Fun facts
- Tiny particles in the atmosphere, called 'condensation nuclei' (like dust or pollen), are essential for water vapor to condense upon.
- Clouds are essentially visible masses of condensed water droplets or ice crystals.
