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.
What holds more water hot air or cold air?
cold air !
Why the amount of water vapour has decreased?
Because people are using more hot water for almost everything. For example when someone is cooking with water they are boiling it which is makeing it turn into water vapor.
What would happen if the air in the upper atmosphere were warmer than the water vapor in the air?
It is impossible for the water vapour in the air to be at a different temperature from the air of which it is a part. However warm air can hold more water vapour than cool air. Thus when air is warming up there are unlikely to be any clouds (clouds are caused by water vapour condensing out of air).
Why is it colder on mountaintops than in the city?
It's cold on top of mountains because expanding air becomes cooler by adiabatic expansion. If you let the air out of your tires, the valve stem becomes cold. It's the same phenomenon. Mountain tops also have less overlying water vapor, so they are cooled by radiation to space more strongly than the low lands.
Does hot air hold more water vapor than cold air?
Yes.
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.
Can warm air hold less water vapor than cold air?
no, warm air holds more water vapour than cold air
Can hot air or cold air hold more water?
warm air hold more water vapor...unless it doesnt like sandwiches between its toes at 5 o'clock in the after noon
Why you see your breath on a cold day?
What you see is water vapor. The air that you exhale contains water vapor. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapr in the air. (the maximum amount of water vapor that the air can hold at that temperature) The colder the air, the less water vapor it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapor. When the air becomes saturated, (relative humidity is 100%), the extra water vapor will condense, allowing you to see your breathe on cold days.
True or false more Water vapor is held in cool air then warm air?
false...air has no ability to "hold" water vapor
What is the substance the makes a window fog up when you breathe on it?
It's the water vapor in your breath, after it becomes liquid water. Warmer air is able to hold more water vapor than cooler air. When you breathe onto a cold surface, the air in your breath is cooled, and it can't then hold as much water vapor as it did when it was warm. So some of the vapor condenses out ... becomes water instead of vapor ... and the condensed water collects on the glass. Exactly the same process is responsible when you exhale into cold air and you "see your breath".
Which provide more vapor in a bottle hot water or cold water?
hot
Why does warm air hold more water vapor then cold air?
Because Water vapor is why the air is warm More specifically the Evaporation/precipitation cycle puts heat into the air via water vapor carrying heat from the surface of the earth into the air If the Surface is hotter then more evaporation happens and in turn more heat gets into the air with the associated humidity
Why can't cold water hold much more water vapor?
Because as the warm air is lifted, it cools and condenses, forming cloudsbecause molecules in cold air don't stick together as much as warm air
Humidity is the amount of water vapor in the air at a given time At warm temperatures air can hold more moisture than it can at cold temperatures Relative humidity is the amount of vapor the air you?
specific humidity
What is an important property of air circulation?
cold air sinks, warm air rises, and warm air can hold more water vapor than cold air can.
