dew point-the temperature at which the water vapor in the air becomes saturated and condensation begins.temperature-the degree of hotness or coldness of a body or environment (corresponding to its molecular activity).ew point. The temperature at which air becomes saturated with water vapor and dew forms. The dew point varies depending on how much water vapor is in the air.
The dew point is the temperature to which air must be cooled to become saturated with water vapor. When further cooled, the airborne water vapor will condense to form liquid water . When air cools to its dew point through contact with a surface that is colder than the air, water will condense on the surface.
