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

Absolute humidity __________________ (select all that apply).

The amount of water vapor, by mass, in each cubic unit of air Can be measured using several different types of mass ratios Is also known as the vapor density

The water vapor can enter the atmosphere because of _______________ . (Select all that apply)

Wind blowing over the surface of the water Evaporation Increased temperature of water Transpiration Decreased pressure of water

Relative humidity is the amount of water vapor in the air,

compared with the maximum amount of water vapor that the air can contain at that temperature

Density equals mass divided by volume. The vapor density equals the mass of water vapor divided by the _____ ______ of ___

volume ... dry air
