What is the amount of water vapor in the air compared to the amount that could be in the air at that temperature?
relative humidity
What term is defined as the amount of water vapor in the air compared to the amount of water that the air can hold?
This is the measure of relative humidity. At 50 percent relative humidity, the air is holding half of what it could. It is relative humidity because it is related to the temperature and pressure of the air.
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.
How can relative humidity and dew point be used to predict the weather?
Relative humidity expresses a percentage of humidity in the air to the maximum amount of humidity that could be in the air. For example: when the temperature rises the air will be able to hold much more humidity so the relative humidity will drop.
If temperature remains unchanged and mixing ratio decreases how will relative humidity change?
The relative humidity will decrease
What would happen to the relative humidity value if the temperature increased to 25 degrees?
If nothing else changes, the relative humidity will fall.
Which is the comparison of the amount of moisture in the air to the amount of moisture it can hold?
relative humidity
Amount of moisture in air compared to amount needed in saturation?
Relative humidity.
What is the amount of water vapor in the air compared to the amount that could be in the air at that temperature?
relative humidity
What can cause changes in relative humidity?
Either dehumidify (remove water vapour), rehumidify (add water vapour) - both at constant temperature, or raise temperature (which will lower relative humidity), or lower temperature (which will raise relative humidity).
What should the low and high end for humidity temperatures for your home?
30 to 50% of Relative humidity - the relative part of relative humidity being relative to the temperature.
How much water vapor is needed to saturate the air?
This is called the relative humidity. It changes due to evaporation and precipitation, and warm air can hold more water than cooler air.
What is the average humidity in baton rouge la US?
Average Relative Humidity: Baton Rouge Relative Humidity (Morning) 89% Baton Rouge Relative Humidity (Afternoon) 62%
The actual humidity divided by the saturation humidity is the?

Relationship between evaporation and relative humidity?
The higher the relative humidity is the lower rate of evaporation.
