Answer:
Dew point is the temperature at which condensation happens. ... When warm air hits the cold surface, it reaches its dew point and condenses. This leaves droplets of water on the glass or can. When a pocket of air becomes full of water vapor, clouds form.
Step-by-step explanation:
The temperature at which a material changes from a gas to a liquid; the same as the boiling point. Condensation is the process by which water vapor (gas) in the atmosphere turns into water (liquid state). It is the opposite of evaporation. ... As the surrounding temperatures fall (cool), the water vapor turns into very tiny particles of water and ice crystals.
