Why does relative humidity not give an accurate indication of the actual amount of water vapor in the air?
Because it is relative to temperature!
What is the difference between relative humidity and actual humidity?
Humidity is the amount of water vapor at any given time and relative humidity is the amount of water vapor in the air compared to the greatest amount it can hold at that air temperature.
What is the relative humidity of air filled to half its capacity?
Relative humidity becomes the ratio between the actual amount of water vapor present to the capacity that the air has at a particular moment. Just to be an optimist, if the glass is half-filled, the relative humidity is 50 percent. If the glass is three-quarters filled, the relative humidity is 75 percent.
Which condition is the actual amount of water vapor in a mixture of air and water?
relative humidity
What is the formula to measure relative humidity?
HR= actual vapor pressure/ saturation vapor pressure

The actual humidity divided by the saturation humidity is the?
relative humidity
What is the difference between relative humidity and actual humidity?
Humidity is the amount of water vapor at any given time and relative humidity is the amount of water vapor in the air compared to the greatest amount it can hold at that air temperature.
How do relative humidity and mixing ratio differ?
Relative humidity indicates how near the air is to saturation, while mixing ratio shows the actual quantity of water vapor in the air.

What does it mean when humidity is 100 percent?
This is called relative humidity. It is the ratio between the actual humidity, and the humidity for saturated air - that is, the maximum amount of water air can hold. This saturation point is dependent on temperature.
What is difference between monthly average max relative humidity and min relative humidity?
Either you have answered your own question in the question itself, or the question is essentially unanswerable - it depends on the actual meaning of the question. Do you want to know the difference in meaning beweeen the two terms, or the difference in the actual figures? The latter is unanswerable.
What do you call the comparison of the actual amount of water vapor in the air to the amount of water vapor in the air if it were saturated?
This is called the "relative humidity."
What is the comfortable room humidity?
Humidity ratio or relative humidity id the ratio of the actual mass of water vapour that would saturate the air at the same temperature, the comfortable room humidity is 50%.
When air is cooled what happens to Relative Humidity?
Yes. Relative humidity is the amount of water vapor actually in the air compared to the amount that could be in the air (saturation point) at the exisiting temperature. So, if the temperature of the air changes and the amount of water vapor in it does not, the relative humidity will be different. But, if the temperature of the air changes and so does the amount of water vapor in it, then the relative humidity could be the same as before the temperature change. That is to say that the air could contain the same percentage of water vapor that it could hold at each temperature, even though the actual amounts are different.
