If air cools what happens to the amount of moisture that the air can hold?

It decreases. As air cools, mist, then clouds, then rain / snow forms... as the moisture is displaced.

The amount of moisture air can hold increases as the temperature of the air gets?
warmer
Why does water stick to the outside of a cup when it's hot?
Relative humidity is the ratio of the amount of water air is holding to the amount of water it can hold. The warmer air is, the more water it can hold. Therefore, as air temperature drops, relative humidity increases, even when no additional moisture is being added to the air. If the temperature continues to drop after the relative humidity reaches 100%, the excess moisture gets condensed out of the air. That is why dew forms during the night. The cold cup of water cools the air around it by conduction, so that cooler layer of air in contact with the cup loses its ability to hold its moisture, and the excess moisture condenses onto the cup.
How does air temperature affect precipitation?
Warm air holds more moisture than cold air. When the air has reached "saturation point" (ie. it cannot hold any more moisture), it is more likely to cause precipitation as the oversaturated air forms moisture droplets that fall as precipitation. One of the major causes of precipitation is when warm air cools rapidly (for example, when it rises after hitting a mountain front or other landmass). As the warm air cools, it loses its ability to retain moisture and becomes saturated, thus creating precipitation.
What is the difference between dew point and precipitation?
The relative humidity is a ratio of the amount of water in a given air over the amount of water that could be held in that same parcel of air. This number will vary as the temperature rises and falls as warmer air can hold more water than cooler air.
What is best for a lawn on sandy soils is it best to mulch the lawn or remove the clippings each mowing How much is a good amount of mulch to build up Does mulch hold moisture and prevent rapid drough?
The grass clippings provide a great source of nitrogen for the grass. It is best to leave the clippings. It does help retain moisture. The grass clippings can even be used as a mulch for plant beds.
Describe what happens when the dew point is reaached?
As air gets colder, it can't hold as much moisture. So if the air cools enough, the humidity will reach 100% capacity and the water will be forced to condense.
How can it be foggy when it's cold?
The general answer is that fog is caused by condensation of water in the atmosphere. It's like a cloud, except that the cloud is in contact with the ground. That's what fog is. Air has moisture in it, and the amount varies. Also, the amount of moisture that air can hold varies as a function of temperature. The warmer it is, the more moisture that air can hold. But if it cools off, air can't hold as much. Fog forms when the temperature drops to the point where the air cannot hold all the moisture in it at that temperature. This at 100% relative humidity, which is called the dew point. Fog begins to form as air, which had previously been warmer and had moisture in it, cools until it reaches the dew point. Then we'll see tiny droplets of water forming in the air close to the ground, which is fog. A link can be found below.
Which is the comparison of the amount of moisture in the air to the amount of moisture it can hold?
relative humidity
What is relative humidity in terms of moisture and temperature?
relative humidity is the amount of moisture that air can hold in a certain temperature
Why does Relative Humidity increase when air cools?
Relative humidity is a measure of how much moisture is in the air relative to how much the air can hold. All the matters in the case of the latter is the air temperature. So if you cool the air temperature, the air can hold less moisture. Therefore, the air now has a larger percentage of moisture relative to what it can hold.
If the gas from dry ice is colorless and clear why does it form clouds of white vapor?
Air holds moisture. The warmer the air, the more moisture it can hold. So when warm air holding a fair amount of moisture comes in contact with the very cold dry ice, it cools down, and some of the moisture condenses out into those clouds you're seeing because the colder air is no longer capable of holding it.
If the amount of moisture stays the samewhat happens to the relative humidity when the air temperature decreases?
relative humidity increases. at a lower temperature, the air can hold less water vapour.
How does a ground fog come about?
Water vapor in the air condenses when the ground cools at night. the cooler ground (often due to radiation into space when it is clear) cools the air near the ground. This cooler air cannot hold as much moisture as warm air and the moisture condenses as fog.
The amount of moisture air can hold increases as the temperature of the air gets?
warmer
What is dew and how is it different from frost?
Air has a certain amount of moisture in it at any given time. Warm air can hold a lot more moisture than cool air. On a summer day with moderate humidity, we don't notice the moisture in the air. At night, when the air cools down considerably, the cooler air can't hold all of the moisture, so some of it precipitates out of the air onto whatever surfaces the air surrounds. That's dew. If it becomes a very cold night, the dew freezes. That's frost.
What is the percentage of moisture in air relative to the amount it could hold at a particular temperature?
relative humidity
How does the temperature of the air affect the amount of humidty that you feel?
warmer air can hold more moisture.
