How do use the word relative humidity in a sentence?
Relative humidity means the percentage of water vapor in the air compared to the total amount that could be contained. Or the measure of the amount of water vapor that air is holding compared to the amount it can hold at a specific temperature. This is different at different temperatures. Here are a couple of sentences:1. The relative humidity is 10 percent.2. We studied relative humidity in class.3. Saturation air has a relative humidity of 100 percent.
A psychrometer gives the same reading on both thermometers what is the relative humidity?
100% because, let's say that both the thermometers have a reading of 66o degrees celcius. 66o is 100% of 66o, so the relative humidity is 100%.
Will it rain when the relative humidity reaches 100?
It can go either way.
How long does it take for one milliliter to evaporate?
Depends on the rate of supply of heat and the relative humidity. It could take forever (100% relative humidity), or be almost instantaneous (pour onto a red hot plate with < 100% humidity).
What unit of measurement measures humidity?
Water vapor in the air is absolute humidity. The ratio of the absolute humidity to the maximum absolute humidity for that temperature and pressure is called the "relative humidity." Absolute humidity is very frequently expressed in terms of grains per pound of air, ppm, or vapour pressure. Relative humidity is usually expressed as a percent.Relative humidity, expressed as a percentage from 0% to 100%, is the amount of moisture in air divided by the total possible amount of moisture in air. Unfortunately, the total possible amount changes when the temperature changes, so the relative humidity can change without adding or removing any water.Another measure is dew point, which is the temperature at which water would condense. It doesn't change with temperature.The lowest measured relative humidity in Phoenix, AZ, USA, is 2%--pretty dry. Sometimes the dew point is below 0 degrees, also pretty dry. (Celsius or Fahrenheit? Both!)
Would the average relative humidity on a rainy day be closer to 100 percent humidity or 50 percent humidity?
The average relative humidity on a rainy day would be closer to 100 percent humidity. Rain adds moisture to the air, increasing the humidity levels to near saturation point. This leads to a higher average relative humidity compared to a non-rainy day.
What does it mean when relative humidity is 100 percent?
It is raining
What is air that has 100 percent relative humidity said to be?
Saturated
What happens when air reaches its dew points?
relative humidity is 100 percent.
How long would it take for water to evaporate if the relative humidity was 100 percent?
Water would not evaporate at 100 percent relative humidity because the air already holds the maximum amount of water vapor it can. This means no additional water can evaporate into the air until the humidity decreases.
What type of air has a realative humidity of 100 percent?
That would be "dewpoint"...When the air temperature falls to the dewpoint (or dewpoint rises to the air temperature), then you have 100% relative humidity.
What is the percent of relative humidity when raining?
Relative humidity can vary during rain, depending on factors such as temperature and amount of precipitation. Generally, during rain, relative humidity tends to be close to 100% due to the presence of moisture in the air from the rain.
If the specific humidity of air is 10 grams per kilogram and the capacity of the air is 50 grams per kilogram the relative humidity is?
The relative humidity is calculated as specific humidity divided by capacity, then multiplied by 100 to get a percentage. In this case, the relative humidity would be 20%.
Why does relative humidity rarely reach 100 percent in polluted air conditions?
Pollutants in the air can serve as condensation nuclei, promoting the formation of cloud droplets at lower humidity levels compared to clean air. This can result in clouds forming before humidity levels reach 100 percent. Additionally, pollutants like fine particles can absorb water, reducing the amount available for condensation, which can prevent humidity from reaching 100 percent.

Is air with 100 percent relative humidty said to be dry?
No, air with 100 percent relative humidity is not considered dry. It means that the air is holding the maximum amount of water vapor it can hold at that temperature, making it saturated. Dry air would have a lower relative humidity percentage.
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.
