In the lessons

In science lessons condensation is part of the water cycle (evaporation, condensation, precipitation) and a change of state from gas to liquid; it explains clouds, dew and misty mirrors. Phrases: «the water cycle», «condensation on the window».

Examples

• Condensation forms clouds in the sky. tree →
• A cold can of drink gets condensation on the outside. tree →
• Evaporation, condensation and precipitation make up the water cycle. tree →

Note

Uncountable. Verb: condense. Opposite process: evaporation (liquid to gas). Trap: the water on a cold glass did not leak through the glass; it came from water vapour in the air.
