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.
Condensation takes place when the air becomes saturated(100% RH).The air becomes saturated when(1) the air temperature becomes equal to dew point temperature, or(2) moisture i â¦ s added to air till condensation takes place which means the dew point temperature should be raised to air temperature.
