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!)
How to use 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. This is different at different temperatures. Here are a couple of sentences.The relative humidity is 10 percent.We studied relative humidity in class.
Which term means the amount of water vapor in the air?
The term is humidity.It is usually expresed as "relative humidity" which is the comparison between the amount in the air and the maximum that it can hold at a given temperature.Humidity
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.
What is a sygrometer?
There is no such thing as a sygrometer, but a hygrometer is a device that is used to measure the humidity of the air. It can indicate relative humidity or absolute humidity.
