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.
What determines the temperature of condensation or sublimation is the amount of moisture in the air, the greater the amount of water vapor, the higher the condensation temperature. During summer it is not uncommon to have a dew point of 70Â°F in the eastern United States.
