Give an example of Dew point???

Question

What's this? Dew point and an example? I am confused. Please help me I have a test Tommorrow!

Answer 1

The dew point or dewpoint of a given parcel of air is the temperature to which the parcel must be cooled, at constant barometric pressure, for the water vapor component to condense into water, called dew. When the dew point temperature falls below freezing it is called the frost point as the water vapor no longer creates dew but instead creates frost or hoarfrost by deposition
