Relative Humidity is actually measure the amount of moisture in the air. It depends on how much of the air has water in it. Let's say that the RH is 50%, that means 50% of the air has water in it.

∙ 9y agoRelative humidity is the ratio of partial pressure of water vapor in a mixture to the saturated vapor pressure of water at a particular temperature. From this, a percentage will be reached which is the relative humidity.

∙ 8y agoRelative humidity is the percentage of water vapor in the air compared to the maximum amount of water vapor that air can contain at a particular temperature.
Relative humidity can be measured by an instrument called a psychrometer.

Does relative humidity measure how hot it feels?
False
How can relative humidity increase diffusion rate?
Relative humidity increases when the amount of moisture air can hold increases. The increase can be caused by the introduction of more moist air, OR a temperature drop of the air/moisture mixture without a loss of moisture. Colder air will hold less moisture than warm air; as the temperature goes down the amount of moisture relative to what the air can hold increases.
What is the amount of water in the air compared to the amount of air can hold is called?
Relative humidity.
What instrument measures relative humidity using the electrical conductance of the chemical lithium chloride?
Hygrometer
Why 75 percent relative humidity at 89F the same as 75 percent Humidity at 25f?
Relatively it is the same (75%) but the absolute amount of water vapor differs very much (power R.H. at lower temp's)
What humidity is a measure of the amount of vapor that air is holding?
Relative humidity
Does relative humidity measure how hot it feels?
False
An instrument that measure relative humidity is called a?
psychrometer
What are the units that a sling psychrometer measure?
Relative humidity
Is a measure of water vapor in the air compared to the amount that could be held at a specific temperature?
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.

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.
What is the differences between relative humidity and humidity?
Humidity is the amount of water vapor present in the air. The relative humidity is the measure of the amount of water vapor present in the air compared to the amount needed for saturation.
How was the Hygrometer used?
hygrometer used to measure density of relative humidity in air by using a sensory element such as a hair
How can you measure ralative humidity in a kitchen?
The relative humidity (RH) in a kitchen can be measured by using a humidity gauge. A maximum indoor relative humidity of 55% RH may be acceptable, but a 50% RH better is better.
What instrument Measures and records humidity and air pressure?
2 instruments are required to accomplish these measurements:a barometer to measure atmospheric pressure.a hygrometer to measure humidity.
What does a phsycrometer do?
A psychrometer is an instrument commonly used to measure the relative humidity.
