How does water vapor enter the air?
Water vapor enters the air as water at the surface evaporates or as plants transpire water vapor from their leaves.
What are the water droplets on cars or grass in the early morning?
The water droplets known as dew form when the air temperature passes below the "dew point" and water vapor condenses from the air onto the cooler objects. When cooled, air can no longer hold as much moisture.
Why does relative humidity decrease after the sun rises and increase after the sun sets?
"Because relative humidity is related with the temperature of the air. Relative humidity is the rate of water vapour to the maximum amount of water vapour can air hold at that temperature. The amount of water vapour that air can hold is increses as the temperature of the air increases. If the air holds same amount of water while the temperature is incresing, relative humidity of the air decreses because maximum amount of water that air can hold increases and the rate of humidity to tha maximum humidity decreses."Someone had given this answer, and it is partially correct, however, their bizarre English and grammar skills make it hard to understand. I think what they meant was that relative humidity is the amount of water vapor in the air, compared to what the air can "hold" at a given temperature. As temperature increases, the amount of water vapor or moisture the air can hold does as well.So, after the sun rises the temperature of the air increases, so does the amount of moisture the air can hold and the actual amount of water vapor in the air may stay the same, thus decreasing the relative humidity. The opposite happens at night.Relative humidity = (actual vapor density/ saturation density) x100%
Explain why it is difficult to include water vapor in a graph that shows the percentages of various gases in the atmosphere?
The amount of water vapor in the air varies considerably depending on climate and weather. In a desert water vapor may account for a tiny fraction of a percent of the air. In a tropical rainforest during a storm water vapor may account for as much as 4% of the air.
When water rises in the air what is it called?
water vapor
What type of air can't hold much water vapor?
cold air
How much water can the air hold when the relative humidity of the air is 25?
how much water vapor can a cubic meter of air hold at 25 centigrades grades?
If cold air mixes with air that has a lot of water vapor what will happen to the water vapor?
It may condense into clouds, or into precipitation, because cooler air cannot hold as much water vapor as warmer air.
Why is there a limit on the amount of water vapor the air can hold?
It takes a lot of energy to turn water into water vapor. The amount of energy that the water gains to turn into water vapor begins to be transferred into the surrounding air. If the air is willing to take on more energy the water vapor condenses quicker. This is why hot air will hold more water vapor than cold air.
What data would be use to find out how much water vapor is in the air?
Look in the weather reports for "Relative Humidity". It is a percentage of how much water vapor is in the air compared to what the air can actually hold at a given temperature.
What happens to the air ability to hold water vapor as the air gets warmer?
As the air gets warmer, it's ability to hold water vapor increases.
What happen to air's ability to hold water vapor as the air gets warmer?
As the air gets warmer, it's ability to hold water vapor increases.
What factor most affects the amount of water air can hold-?
Water vapor in the air compared to the amount of water vapor that air could hold at a given temperature.
What happens to the airs ability to hold water vapor as the air gets?
As the air gets warmer, it's ability to hold water vapor increases.
What happens when air is humid?
Humidity (relative) is the amount of water vapor in the air, expressed as a percentage of the maximum amount that the air could hold at the given temperature; the ratio of the actual water vapor pressure to the saturation vapor pressure. So pretty much the air is moist and heavy.
Why relative humidity increases as temperature decreases and vice versa?
"Relative" humidity means how much water vapor there is in the air compared tohow much the air could hold at that temperature.And warmer air can hold more water vapor. Cooler air can hold less.So ... if there's a certain amount of water vapor in the air, and the air temperaturedrops, the air can now hold less at the reduced temperature, so the amount that'sthere is now a greater fraction of how much the air could hold ... higher relativehumidity.See the link below for the formula of Buck; the effect of temperature is evident.
What happens to airs ability to hold water vapor as the air gets warmer?
As the air gets warmer, it's ability to hold water vapor increases.
