When the dew point goes below freezing, the more applicable temperature is the frost point, at which water vapor will freeze out of the air. The frost point is higher than the dew point, because ice holds water molecules better than liquid water.

How does water vapor become frost?
When water vapor meets a surface that is below the freezing temperature and below the dew point, it turns into frost.
What is the dew point and what happens when it falls below the dew point?
The Dew Point is the temperature at which the air is at 100% Relative Humidity. If the temperature fall below the Dew Point, then there is more moisture in the air than it can hold, and water condenses in the form of dew, mist, rain, etc.
Is it true that water usually condenses when air temperatures falls below dew point?
Water can start to condense from the air when the temperatures drop below the dew point. It happens when the ground is cold or when the air above the sky is cold.
When are clouds formed by ice crystals instead of drops of liquid water?
When the dew point is below freezing, the liquid water may change directly into ice crystals.
Clouds form when the air is cooled below the?
Dew point
What happens when the dew point is below freezing Is?
it means that liquid water droplets cannot form, instead water precipitates directly as frost.
Describe what happens when air is cooled to its dew point?
The dew point is the varying temperature at which atmospheric humidity condenses. If the air temperature drops below the dew point, dew and condensation form.
Why isn't dew point always the same?
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.
What happens when air is cooled below its dew point without condensation?
supercooled

Which region of India has most fog and dew and mist?
In the northern region,where the cloud temperature and ground temperature remains below the freezing point,prcipitation occurs in the form of fog,mist and dew.
How does dew get on the grass?
As air gets colder, the amount of water it can hold as water vapour goes down. It reaches a point where the air releases the water as dew but stays saturated with water vapour. If this point is below the freezing point of water, it is deposited as frost.
Is it true that water usually condenses when air temperatures falls below dew point?
Water can start to condense from the air when the temperatures drop below the dew point. It happens when the ground is cold or when the air above the sky is cold.
The name given to a liquid drop of dew that freezes when air temperature drops below freezing is?
frozen dew
What is the relationship between dew and frost?
When dew forms in the winter, it forms at night and its colder at night so the dew freezes at that point in freezing.
When are clouds formed by ice crystals instead of drops of water?
When the dew point is below freezing, the liquid water may change directly into ice crystals.
