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.
In the example just given, the dew point before condensation was 10 degrees Celsius. Dew point may be higher or lower, depending on the amount of water vapor in the air. The more water vapor the air starts with, the higher its dew point. When air cools to slightly below the dew point, water vapor begins to condense.
