Relative humidity is a comparison of the amount of moisture that air is holding compared to the maximum amount it could hold at a given temperature. If it's holding all that it can, the relative humidity is 100%.

Air that holds the maximum amount of water at a given temperature is said to be what?

Relative Humidity.

What is the relative humidity of the air that holds all the water it can at a given temperature?

saturated (:

When relative humidity is reported what is the unit?

Relative humidity is reported in percentages. The percentage relates to the amount of water vapor air of a given temperature holds when it is saturated. So the humidity is reported as 50%, if the amount of water vapor in the air is half of what the air could hold at its current temperature.

What is the relative humidity if air that holds ll the water it can?

what is the relative humidity of air that holds all the water it can

Why does relative humidity decrease after the sun rises and increase after the sun sets?

"Because relative humidity is related with the temperature of the air. Relative humidity is the rate of water vapour to the maximum amount of water vapour can air hold at that temperature. The amount of water vapour that air can hold is increses as the temperature of the air increases. If the air holds same amount of water while the temperature is incresing, relative humidity of the air decreses because maximum amount of water that air can hold increases and the rate of humidity to tha maximum humidity decreses."Someone had given this answer, and it is partially correct, however, their bizarre English and grammar skills make it hard to understand. I think what they meant was that relative humidity is the amount of water vapor in the air, compared to what the air can "hold" at a given temperature. As temperature increases, the amount of water vapor or moisture the air can hold does as well.So, after the sun rises the temperature of the air increases, so does the amount of moisture the air can hold and the actual amount of water vapor in the air may stay the same, thus decreasing the relative humidity. The opposite happens at night.Relative humidity = (actual vapor density/ saturation density) x100%

What is the relative humidity of air at its dew point?

100%. The dew point of air is the temperature at which the air will become saturated. Saturation describes the condition of the air when it contains the maximum possible amount of water vapor. Relative humidity describes the percentage of the maximum possible water vapor content that the air holds at a given time (For example, the air may be able to hold 10 g/m3 of water vapor at a given temperature. It it contains 3 g/m3, it contains 30% of the maximum, so its relative humidity is 30%). When air reaches its dew point, it has become saturated. This means that the air now holds the maximum amount of water vapor possible -- 100% of the maximum. Therefore, relative humidity at the dew point is always 100%.

What does a relativehumidity of 70 percent mean?

It means that at the given air temperature the air contains 70% of the amount of moisture the air can hold before condensing as water. It is relative because hotter air holds more water, so it it a lot more moist at high temperatures for a given relative humidity.

How to Calculate actual humidity from relative humidity?

One can calculate the absolute humidity (AH) from the relative humidity (r) using three equations: (1) the equation for mixing ratio, (2) an equation for relative humidity expressed in terms of mixing ratio, and (3) the Clausius-Clapeyron equation, which relates saturation vapor pressure to temperature. The result of combining the three equations is: AH = (1324 r/T) [exp {5417.75 (1/273 - 1/T)}] where AH is expressed in grams per cubic meter, T is temperature in Kelvin, r is relative humidity (range is 0 to 1), and the relation holds true for T>273. For T<273, replace 5417.75 with 6139.81.

What is the ratio of the amount of water vapor in the air to the maximum amount of water vapor it can hold at that temperature?

The percentage of water vapor present compared to the maximum possible amount is called the relative humidity. At 50% relative humidity, the air holds half of the total amount that it could hold. In some cases, more water vapor may be added (or the temperature lowered) to increase the percentage above 100%.

What is air that holds all water it can at a given temperature?


Do humidity holds water vapor?

Humidity is the measure of how much water vapour there is in the ambient atmosphere. In a similar way, though not quite, that temperature is a measure of how much heat a substance has.

Does humidity have any link with temperature change?

I came across this question while trying to find an answer to a similar question. The answer to: "Does humidity have any link with temperature change?", is yes. Warmer air can hold more moister, and colder air holds less moisture. That is why we get so dry in the winter and run humidifyers. the relative humidityoutside may be 75%, but when that same air is inside and warmer, it has the same amount of water vapor in it, but could hold more. so the relative humidity is less. Think of air like a quirky milk container. When the container is cold it holds exactly 1 gallon. and if there were two quarts of milk in it, it would be 50% full. now leave the lid on, so no milk can get in or out. when the quirky milk container gets warm, it expands to two gallons. there is still only two quarts of milk in it, because we never took off the lid. now the container is only 25% full. Relative Humidity works the same way. when it is cold outside, air can only hold a certain amount of water vapor. when that same air comes inside and gets warm, it can hold a lot more, so realatively speaking, the container, I mean air, has a smaller percentage of fullness, I mean, Humidity in it. Hope this helps. I was looking for the exact amount of percentage changes given amount in now, and temperature change.

What is the relative humidity of 25 degrees and 28 degrees?

There is no fixed relative humidity by temperature. There is an absolute maximum, determined by temperature and pressure. At 25 degrees C, air can hold about 23.04 grams of water per cubic meter (g/m3) At 28 degrees C, air can hold about 27.4 grams of water per cubic meter (g/m3). This is about 19.3% more water vapor. *This is based on standard atmospheric pressure. Denser air hold more, thinner air holds less.

Is cold air more humid than warm air?

Cold air holds much less moisture than warm air, so often (but not always) the absolute humidity is less in cold air. Relative humidity is what is much more often reported, and this will not differ between cold and warm because it is relative to how much the air can hold.

What does humidity depend on?

The level of humidity in the air depends on two factors. (1) Temperature. Colder air holds less, because more humidity will condense into water. (2) Barometric pressure. The more pressure the atmosphere is under the less water vapor it can hold.

What holds true for volume if the temperature of a given amount of gas increases and pressure remains constant?

How does the amount of water affect how long it takes to freeze?

Mass holds temperature--the more mass, the better it holds temperature...but, conversely, the longer it takes to get it to temperature all the way through.

Why is it more humid when its warmer?

The ability of air to hold moisture is a function of temperature. Warm air can hold more moisture than cold air. In fact, this is why drops of water (condensation) appears on cold objects in a warm, humid room. The cold object cools the air around it causing the water vapor it holds to condense out and form droplets on the cold object. The water on the object is water that is no longer in the air, so the relative humidity of the air is lower.

Do dry air and clear skies keep the desert warm at night?

In hot deserts, such as the Sahara desert, there may be a high diurnal temperature amplitude between day and night, usually around 20 °C : it can be 40 °C in the day while the nighttime temperature could drop at 20 °C easily. The higher diurnal temperature amplitude in the hot deserts are caused by the excessively dry air and cloudless skies. During the day, the Sun heats up the ground and the atmosphere with his rays. During the night, after the sunset, the Earth sends back the accumuled heat in the day to the atmosphere by emitting an infrared radiance, which cools off the ground and the air. But at the night the cloud cover and the humidity contained within he air holds the heat accumulated during the daytime, which reduces the diurnal temperature amplitude but in the hot deserts where cloud cover is extremely rare and the relative humidity is exceptionnally low mean it won't hold the heat of the Sun which cause larger dirunal temperature amplitude.
