relative humidity?

Question

how would u know which air at different locations has the greatest capacity to hold water vapor?
using the relative humidity?

for example:
1)Courtyard relative humidity 35.0
10) Outside front relative humidity 84.0

which air has the greatest capasity to hold water vapor? and how did u find it

Answer 1

Only the air temperature decides the capacity of air to hold the water vapour.The more the temperature,the more water vapour the air can hold.
If you know the dry bulb temperature(air temperature) and the wet bulb temperature,then you can calculate the relative humidity and thereby you can find out whther the air is holding the maximum amount of water vapour or not.If the relative humidity, thus calculted is 100 percent, then it is holding the maximum amount(for that temperature).

Answer 2

The % of water that the air will hold at a given temperature. You have to know the temperature though to know how much water the air is holding. 85 % at 30 degrees may be only a small amount or water per a cubic foot of air compared to only 30 % at 120 degrees. The hotter the air is the more water it has a potential to hold. For an example: If a cubic foot of water at 100 degrees will hold a cup of water, then if it is now holding a half a cup of water the relative humidity is 50%, since it is holding 50% of it's potential. If the same cubic foot of air is at 80 degrees it may only have a potential to hold a half a cup of water so if it was holding the same half a cup of water as the 100 degree air it would be at 100% relitive humidity. Of course my numbers are not true, they are only examples to show the relation between the water, air and temperature. I think in reality, if it is about 20 % relitive humidity at 100 degrees, it will reach 100% by about 50 degrees with the same amount of water per cubic foot or whatever cube you want to use.

Answer 3

it all depends on the tempreature and how the air acts around it.. if it was too hot or too cold it will make a big difference.. rlative hunidity is the amount of saturated water vapor that the air can hold..
