What is the temperature when snow falls when humidity air cools below and what degree.?

As snow falls it will evaporate if the surrounding air is drier, and the energy required to turn water or ice into a gas is taken from that air and the air cools. Eventually it cools to saturation, where the temperature and dew point are equal or very nearly so. This temperature - where the dew point and temperature "meet" if you increase the relative humidity to saturation - is the wet bulb temperature.

How does molten lava change into a solid?
It cools down and essentially freezes as the temperature drops below the meltng point.
How do you use a wet bulb thermometer and a dry bulb thermometer?
as the air passes over the wet bulb thermometer the water in the cloth evaporates. as the water evaporates the cloth cools. if the humidity is low the water will evaporate more quickly and the temperature reading on the wet bulb thermometer will drop. if the humidity is high only a little bit of water will evaporate from the cloth of the wet bulb thermometer and the change in temperature will be small.
How is relative humidity affect by air temperature?
Warmer air is able to hold more water vapour than cooler air. As warm humid air cools, the water vapour condenses out as water droplets.
How does the expansion of air affect temperature?
It cools.
When water vapor in the atmosphere coolsit may form?
Fog or clouds. Air is able to hold a certain amount of water vapor in the atmosphere, and the amount is dependent on the temperature and pressure of the air. Higher temperature air can contain more transparent water vapor than colder air can. We calculate the "relative humidity" of the air as the ratio of how much water the air DOES contain divided by the maximum amount of water that the air could contain, for a given temperature. When air cools, the absolute amount of water contained in the air does not change, but the air's ability to hold it decreases. So as air cools, the "relative humidity" increases. We can also calculate the temperature at which the air is at 100% relative humidity; that is to say, the air can't hold any more water. We call this temperature the "Dew Point". When the air cools down to the "Dew Point", moisture in the air begins to condense onto cooler surfaces, and we call these droplets of water on the grass and trees "dew". If the water condenses into tiny droplets in the air, it will form fog on the ground, or clouds above the ground surface.

What does humidity do for you body?
"its not the heat , its the humidity" usually means it is the the humidity that cools your body temperature down .
Why fog form when humidity is high and temperature is low?
When humid air near the ground cools below it's dew point, Fog is formed.
When the humidity is high and the temperature is low fog often forms why?
When humid air near the ground cools below it's dew point, Fog is formed.
When the humidity is high and the temperature is low fog oftens forms. why?
When humid air near the ground cools below it's dew point, Fog is formed.
Why does your ac not reduce your humidity below 70 percent?
An a/c does not dehumidify, it cools the air. If you need less humidity get a room dehumidifier.
What is the relationship between humidity and condensation?
High humidity will cause condensation on a relatively cold surface, because the thin layer of air surrounding the surface cools below the dew point and can no longer hold the water vapor. Clouds and fog occur because the air temperature has fallen below the dew point .
Condensation of water vapor in the air occurs when the temperature drops below the point at which the air's?
capacity and specific humidity are the same
How does the temperature of the air affect the amount of humidity you feel?
Increase in temperature makes us sweat. Normally when sweat evaporates it takes heat from body to evaporate and thus cools our body. But when humidity is high the sweat is not able to evaporate thus our body is not able to cool. In cold weather we will not experience this as body does not sweat.Thus increased temperature affects the amt of humidity we feel.
How does molten lava change into a solid?
It cools down and essentially freezes as the temperature drops below the meltng point.
What is the percentage of humidity?
The short answer is the maximum percentage of humidity in the air at any temperature is 100%. The percentage of humidity or relative humidity of air is the percent of the maximum humidity or amount of water that the air can hold at any given temperature. Therefore if the relative humidity is 80 per cent at 20 degrees and then the air cools off to 18 degrees the relative humidity goes up even though the amount of humidity or water in the air stays the same. If the temperature continues to drop the relative humidity will continue to rise. Since cool air can hold less air than warm air the relative humidity will eventually reach 100%. If the temperature continues to fall the relative humidity will remain at 100% and water will come out of the air as precipitation.
What cools rapidly at night desert or a swampland?
Due to lack of humidity and cloud cover, the desert cools rapidly after sunset.
