Why relative humidity increases as temperature decreases and vice versa?

"Relative" humidity means how much water vapor there is in the air compared to
how much the air could hold at that temperature.
And warmer air can hold more water vapor. Cooler air can hold less.
So ... if there's a certain amount of water vapor in the air, and the air temperature
drops, the air can now hold less at the reduced temperature, so the amount that's
there is now a greater fraction of how much the air could hold ... higher relative
humidity.
See the link below for the formula of Buck; the effect of temperature is evident.

As temperature increases during the day relative humidity usually?
Decreases.
What does relative humidity do as the temperature decreases?
As temperature decreases, relative humidity increases.** Related Information:This is why a cold front often causes precipitation as it moves through an area.
What weather factor is a hygrometer use for?
Hygrometers measure the relative humidity of the atmosphere. The relative humidity is the ratio between the present water vapor content of the air and the maximum amount of water vapor the air could hold at the same temperature. Cool air will not hold as much water vapor as warmer air. With the same amount of moisture in the air, an increase in temperature decreases the relative humidity, and if the temperature drops, relative humidity increases.
What effect takes place when relative humidity increases or decreases while calibrating the instruments?
Hygrothermal Fluctuations
What happens to relative humidity when temperature rises?
When temperature rises, the capacity of air to hold water vapor increases. Consequently, the relative humidity decreases because the amount of moisture present in the air remains the same, but it is spread out over a larger volume.
What happens to humidity if temperature increases?
The relative humidity decreases

What happens to the relative humidity when the temperature increases and the water vapor stays the same?
it decreases :)
If the amount of moisture stays the samewhat happens to the relative humidity when the air temperature decreases?
relative humidity increases. at a lower temperature, the air can hold less water vapour.
Relative humidity changes with?
Addition of water vapor into the air, removal of water vapor in the air, decreases in temperature, and increases in temperature.
If the air temperature stays the samewhat happens to the relative humidity when the amount of moisture increases?
Relative humidity increases.
If temperature remains unchanged and mixing ratio decreases how will relative humidity change?
The relative humidity will decrease
Condensation increases with greater?
Condensation Increases with relative HUMIDITY.

What are two things that increases humidity?
In terms of RELATIVE humidity, you can either add moisture to the air or lower the temperature.
