How can you have an atmosphere compromised of 78 percent nitrogen 21 percent oxygen and 1 percent others with relative humidity of 4 percent?
When you see a list of the components of air, they refer to DRY air, because the amount of water vapor varies. If the relative humidity is 100% and the temperature is 104F, water vapor would make up 7% of that air. I doubt the dew point has ever hit 104F, so almost certainly it's never been that high and is usually a good bit less. When temperatures drop well into the double digits below 0, there is only a barely-detectable amount of water vapor. So those component lists floating around describes dry air, or the make-up of the air that isn't water vapor. Those numbers are fairly constant whereas if you tried to include water vapor, you couldn't come up with hard numbers because they are all displaced by any water vapor in proportion to how much of the dry air they make up.
Why is it difficult for spacecraft to study Venus?
It is difficult because Venus has a thick atmosphere of methane. The atmosphere is so thick when a NASA probe tried to enter the thick atmosphere it crumbled to piece's. So that's why its hard.
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%
What kind of weather does a cumulonimbus cloud mean?
H20 is getting evaporated and it forms thick cumulonimbus clouds. there could be rain or thunderstorm. It is very hard to tell the weather.
Is water stronger than earth?
Yes because water can dissolve earth. Even though earth can be very strong & hard, after a while, water can dissolve it.
Thick water vapor that makes it hard to see?
Mist and fog.
Why does plain water evaporate faster than salt water?
salt soaks into the water and makes the water hard to evaporate because its too thick. Ms.Melissa is my friend at Charles Ellis
Why is quick'sand so slow?
Because of how thick the sand, water, and clay is all mixed together. That solution makes it thick and slow, but hard to get out of. When you walk through the sand and when you walk through clay, you have to use more muscles because of how thick it is. Mix these with water and salt, and your bound to get stuck.
Why is it hard to include water vapor in a graph that shows the percentages of various gases in the atmosphere?
That's because water vapor is so variable in its concentration in the atmosphere.
What is the chemical in hard water?
Forms of Calcium is what makes hard water hard
What is the hardness in the water?
Forms of Calcium is what makes hard water hard
What occurs when liquid water changes into water vapor?
The water expands... so the volume increases.
What are the advantages of hard water for Brewery owners?
Hard water makes beer less mild than soft water, which is a good thing. Makes the beer nice and stroonggg! :)
Are clouds soft or hard?
Clouds are neither soft or hard. They are made from water vapor so for example when you go through them you come out very wet.
Is calcium found in hard water?
YES, it's is the calcium that makes the water "hard". That is why you use a cleaner that has a calcium remover in it to get those hard water stains off.
Why are submarines built of hard thick sheets of metal?
To withstand high water pressure when they are submerged at sea.
Why does steam come out of cooling towers?
Steam is produced to turn the turbines then it is released through the cooling towers. It is water vapor and if it is cool outside then it forms into clouds because it condenses in the air. During the summertime and when it is dry it is hard to see the water vapor.
