Water Vapor
For every ________ increase in temperature, twice as much water vapor can enter the atmosphere through evaporation.
10°
Given the formula: Relative humidity = Specific humidity x 100% = maximum capacity The maximum amount of water vapor air can contain at a particular temperature is 50 g per kilogram. If the air only contained (specific humidity) 10 g per kilogram, how much water vapor can it contain?
20%
The maximum amount of water vapor air can contain at a particular temperature is 20 g per kilogram. If the air only contained 10 g per kilogram (specific humidity), how much water vapor can it contain? The formula is: Relative humidity = Specific humidity x 100% = maximum capacity
50%
If the air is completely saturated on a cold night how will you feel?
Cold and clammy
