Answer Details
The temperature at which the water vapor in the air saturates the air and begins to condense is known as the "dew point". When air is cooled down to its dew point temperature, the air is no longer able to hold all the water vapor it contains and some of it condenses into water droplets, forming dew. Therefore, the dew point is the temperature at which the relative humidity of the air reaches 100%, and further cooling will result in the formation of dew, fog, or clouds.
