If the air is saturated with water vapor what must happen to the temperature of the air to allow it to hold more water vapor?

it would have to get colder for the water molucules to shrink and more to come in and it woluld allow more space

When an air mass holds as much vapor as it can at that temperature?
It is saturated.
What is mean by saturated liquid and vapor?
Any addition of thermal energy to a saturated liquid will cause it to vaporize. Any subtraction of thermal energy from a saturated vapor will cause it to condense.
What is mean saturated liquid and vapor?
A liquid or vapor is saturated when it is at the temperature and pressure where it would be in equilibrium with the other phase; saturated liquid at the boiling point or saturated vapor at the dew point. If the pressure is raised, the vapor will condense until the pressure is restored to the original pressure or all the vapor is condensed. If the pressure is dropped, a saturated liquid will boil until the pressure rises back to the original pressure or all the liquid has vaporized. If the temperature is increased, a saturated liquid will boil off completely unless the vaporized liquid raises the pressure enough to establish a new equilibrium. If the temperature is dropped, a saturated vapor will condense until the pressure has dropped enough to establish a new equilibrium.
What is the working principle of a condenser?
A condenser rejects heat to the environment to turn vapor into liquid. Ideally a vapor enters the condenser as saturated vapor, meaning it's at the boiling point. The vapor condenses and leaves the condenser at saturated liquid (also at the boiling temperature).
What will happen to the water vapor in the air if the temperature drops as predicted?
When the temperature drops the less water vapor in the air
Why is entropy of saturated liquid lower than saturated vapor for any pure substance?
Because to perform the change of state from the saturated liquid to saturated vapor ( at constant presure ) you have to add heat in the amount of the substance's evaporation latent heat Qev . At constant pressure, temperature will stay fixed at its saturation temperature and the increase in entropy will be (delta S)ev = Qev/Tsat where (delta S)ev is the entropy increment. Tsat is the saturation absolute temperature of the substance. And so the saturated vapor entropy is (delta S)ev larger than the saturated liquid entropy.
What is wet vapor?
Wet Vapour is the region which contains a mixture of liquid and vapour. The liquid is saturated liquid and the vapour is saturated vapour. The temperature stays uniform until the entire phase change is complete.
How do you convert mm Hg humdity to relative humdity in percentage?
From Wikipedia, article "relative humidity": "It is defined as the ratio of the partial pressure of water vapor in the air-water mixture to the saturated vapor pressure of water at the prescribed temperature." So, you somehow measure the partial pressure of water vapor, look up the saturated vapor pressure of water for the current temperature, and take the ratio.
What happen to the molecules of water vapor when the temperature of the gas cools?
the water vapor turns to liquid
What are two ways air can become saturated with water vapor?
To saturate the air with water vapor, you can lower the temperature to it's dew point, and leave out water to be evaporated.
What is relative humidity relative to?
The ratio of a partial pressure of water vapor in an air water mixture to the saturated vapor.
When does a city experience 100 percent humidity?
when the air becomes saturated with water vapor by the temperature of the air reaching the dewpoint.
