Relative Humidity is the measure of water vapour in air.
It is the ratio of the actual water vapour in air divided by the maximum amount the water the air can hold at the existing temperature and pressure.
It tells how fast or slow the water on the body or in clothes will evaporate or in otherwords is the air dry or humid.
Absolute measure of water vapour in air is called specific humidity.
It can be measured as ratio of mass of water and mass of dry air.

What is the amount of water vapour present in air called?
It is humidity.
Is water vapor nitrogen?
No, water vapour is water. Nitrogen is around 72% of the air we breath but is not found in water, steam or vapour.
Humid air is filled mostly with?
The difference between humid and dry air is the amount of water vapour held in the air "water vapor"Humid implies wet. Humid air is largely filled with water particles.
Define relative humidity?
Water can "dissolve" in air. As the temperature and pressure of air goes up, the amount of water that can be held in the air increases. We can measure the "absolute" humidity of air, but this isn't especially useful. It is more handy to know hoe much water is IN the air, as a percentage of the amount of water the air COULD hold. That's "relative humidity". It is important because as the temperature rises, the air COULD hold more water, so the relative humidity falls. As the temperature falls, the relative humidity rises. As the air cools, when the air couldn't possibly hold any more water than it has now, the relative humidity is 100%, and we call this the "dew point", when dew will begin to settle onto the grass. If the air gets much colder, the water will condense out of the air and form FOG.
Does warm humid air feel warmer than warm dry air?
NO! Definitely not.Humid means more water vapour, more water vapour, more heat loss as water vapour is still water and it can conduct heat away from the air and warm dRy air is just warm air basically. =3
What is relative humidity a ratio of?
Relative humidity is the ratio of the partial pressure of water vapour to the saturation vapour pressure of water at the same temperature. Relative humidity depends on temperature and the pressure. Very roughly speaking, it is a ratio of the amount of water vapour in the air compared to the total amount of water vapour that it possible for that air to contain.
The amount of water vapor in the air is called what.?
Humidity is the measurement of the amount of water vapour in the air.
What is amount of water vapour in air called?
Humidity
What is the name of the amount of water vapour in the air?
humidity
What is the amount of water vapour present in the air?
It is humidity.
What is specific humidity and relative humidity?
Relative humidity compares the amount of water vapour present in the air with the amount of water vapour that would be present in the same air at saturation. Specific humidity is the mass of water vapour present per kg of total air.
What is the amount of water vapour called in the air?
That is called humidity.
What common term refers to the amount of water vapour that is held in the air?
Relative humidity is therm used in measuring the amount of water vapor in the air. High humidity can make the temperature feel higher than what the actual temperature is.
What is occurring when you can see your breath on cold days?
The air that you exhale contains water vapour. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapour in the air.(the maximum amount of water vapour that the air can hold at that temperature) The colder the air, the less water vapour it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapour. When the air becomes saturated, (relative humidity is 100%), the extra water vapour will condense, allowing you to see your breathe on cold days.
What is the ratio of RH?
Relative humidity (RH) is the ratio of the partial pressure of water vapour to the saturation vapour pressure of water at the same temperature. Relative humidity depends on temperature and the pressure. Very roughly speaking, it is a ratio of the amount of water vapour in the air compared to the total amount of water vapour that it possible for that air to contain.
What happensin airconditioningwhen humiditylevel is high inatmosphere?
the humidity condences and you get pure water. the air can only hold a certain amount of water vapour, that amount rises with temp so when you cool the air you can have excess water vapour which will condence to liquid water.
If there is a small difference between the wet- dry blub temperatureswhat is the relative humidly?
It means the relative humidity is high. (amount of water vapour in the air is quite close to the maximum amount of water vapour that the air can hold)
