Am I mistaken or are do you in fact mean dew point ? If so this from Wiki...........
The dew point is the Temperatureto which a given parcel of Airmust be cooled, at constant Barometric_pressure, for Water_vaporto Condensationinto water. The condensed water is called Dew. The dew point is a Saturationpoint.
The temperature at which moist air becomes saturated and forms dew is called the dew point temperature.
They are the same.
The dew point controlled the temperature of the air.
The dew point is a measure of the amount of water vapor in the atmosphere. As the temperature gets closer to the dew point, the humidity rises. When the temperature finally drops to the dew point (100% humidity), the the atmosphere is completely saturated with water, and it will start to rain (or snow, if the dew point is below freezing). Since the atmosphere is completely saturated when the temperature is at the dew point, it cannot go below the dew point.
Dew point is the temperature at which air becomes saturated.
The temperature to which air must be cooled to reach saturation is called the dew point.
If the temperature of the ground, grass, and other surfaces is warmer than the dew point of the air that comes in contact with the surfaces, dew will not form. Sometimes this happens when the air is really dry and the dew point is very low.
Because the temperature changes and the dew point is dependent on the temperature.
The symbol for dew point temperature is usually represented as Td.
The dew point temperature is the temperature at which air becomes saturated with moisture and water vapor begins to condense into liquid. Formation of dew occurs when the air temperature drops to the dew point, leading to condensation on surfaces. This temperature varies based on humidity levels; higher humidity results in a higher dew point. To determine the specific dew point temperature at which formation began in a given context, the current temperature and relative humidity must be measured.
Yes, when the dew point temperature and the air temperature coincide, the air is saturated. This is because the air has reached its maximum humidity at that temperature, leading to condensation or dew forming.
The dew point is the temperature where condensation begins.
