Atmospheric pressure is reduced with increasing water vapor because the water has a lower molecular weight than dry air. The same number of molecules occupy a given volume at a given pressure, so the total mass of water vapor laden air is lower than dry air. If you add up the weight of a column of the wet air it will weigh less than the same column filled with dry air, hence, wet air has a lower air pressure.

∙ 11y agoMore water evaporates into the air when the temperature rises, if there are water sources such as ponds or rainfall held in the soil in an area.
When this happens, people sense this as increasing humidity

How does the water vapor content of air change with increasing temperature?
From what I think, as temperature increases, space between molecules of particles of air increases, which now has more space for water vapor to fit in. Also, as temperature increases, more water can evaporate to form vapor, so IF THE QUESTION IS IN RELATION TO A PLACE NEAR A WATER BODY, the water vapor content should increase.
What happens when air is humid?
Humidity (relative) is the amount of water vapor in the air, expressed as a percentage of the maximum amount that the air could hold at the given temperature; the ratio of the actual water vapor pressure to the saturation vapor pressure. So pretty much the air is moist and heavy.
A pure solvent has a vapor pressure the vapor pressure of a solution A.EQUALTO B.LOWER THAN C.higher than?
A solution has a higher vapor pressure than a pure solvent. This is why salt water boils faster than pure water.
What happens after water vapor?
the water vapor would rise up in the sky and then it will become cool, then it will form a cloud
What is the meaning of boiling in science terms?
Actually boiling is a point where the vapour pressure of any liquid (example: water) becomes equal to the surrounding pressure.
Explain why vapor pressure increases as temperature increases?
Vapor pressure increases as temperatures increase because water will evaporate in hot weather. This evaporation rises increasing the vapor pressure. This is why many areas have high humidity in the summer.
How does air pressure change as water vapor pressure increases?
As water vapor increases, pressure decreases due to the fact that water is made up of hydrogen and oxygen, which is lighter than what most of the air is made out of, oxygen and nitrogen.
What happens to the relative humidity if the amount of water vapor in the stays the but the air get coolers?
The relative humidity increases, assuming that the pressure stays the same.
What happens to Vapor pressure of water when mixed with sodium chloride?
your mom happens
Compare the vapor pressure of water at 10 C with its vapor pressure at 50 C?
Vapor pressure of water at 10 0C is less than that at 50 0C because, like gas pressure, as temperature rises, the kinetic energy of particles increases, thus increasing pressure. So the pressure of water vapor at 50 0C has more vapor pressure than at 10 0C.
What happens to vapor pressure if sugar is added to a solution?
When you add a teaspoon of honey to water with vapor pressure, it will reduce the vapor pressure. The sugar in the honey leads to the pressure going down.
What happens to a liquid-vapor system at equilibrium if the temperature decreases?
If the temperature of a liquid decreases, so does the vapor pressure. Clothes dry faster in a warm or hot clothes dryer than they do when hung up in a cool house. The vapor pressure of water is higher when it is warmer in the clothes dryer. Clothes dry faster in the sunshine than in the shade. Sunshine is warmer.
What happens to water pressure as you increase depth?
as water depth increases then so does the water pressure
What happens to the relative humidity of the amount of water vapor in the air stays the same but the air gets cooler?
The relative humidity increases, assuming that the pressure stays the same.
What happens to the relative humidity if the amount if water vapor in the air stays the same but the air gets cooler?
The relative humidity increases, assuming that the pressure stays the same.
What happens to the relative humidity if the amount of water vapor in the air stays the same but air gets cooler?
The relative humidity increases, assuming that the pressure stays the same.
What happens to the relative humidity if the amount of water vapor in the air stays the amount but the air gets cooler?
The relative humidity increases, assuming that the pressure stays the same.
