Question

What is the dew point of air

Answer 1

Dew point is the temperature to which air must be cooled to become saturated with water vapor. When further cooled, the airborne water vapour will condense to form liquid water (dew). When air cools to its dew point through contact with a surface that is colder than the air, water will condense on the surface.[1][2] When the temperature is below the freezing point of water, the dew point is called the frost point, as frost is formed rather than dew.[3] The measurement of the dew point is related to humidity. A higher dew point means there is more moisture in the air.[2]

Answer 2

Answer:

The dew point temperature of air is defined as the temperature to which the air would have to cool in order to reach saturation.
