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 is the formula to measure relative humidity?
HR= actual vapor pressure/ saturation vapor pressure
The measure of water vapor saturation of air is called what?
The answer is actually called: The mixing ratio.
What happens when temperature and dew point are equal?
This is the point at which saturation occurs. This is also signifies 100% relative humidity. If you want to find out how close it is to reaching saturation, all you have to do is find actual vapor pressure (found by temp.), and saturation vapor pressure(found by dewpoint). You can look online for conversion charts. Once you find them, plug them into this equation: actual vapor pressure/saturation vapor pressure x 100%. Your answer should be a percentage. If it's around 60-80 percent, then you know it's cold, and there is high humidity; thus, saturation is likely to occur. If it's around 10-30 percent, then you know the humidity is low and saturation is not likely occur. Warm weather= low humidity Cold weather= high humidity.
What is the temperature at which air can no longer hold all the water vapor?
That's an approximate definition of saturation. And the temperature at which the current amount of water vapor in the air would be the saturation point is called the dew point. The dew point is a measure of absolute humidity.

relative 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 much relative humidity would decrease when temperature rises?
Relative humidity is a ratio between the partial pressure of water vapor and the saturation pressure of water vapor at the current temperature and pressure. If the temperature and pressure change, then the relative humidity will change also. You are correct that higher temperatures allow the atmosphere to hold more water. That means that the saturation pressure of water vapor has increased while the current vapor pressure has remained the same, causing the relative humidity to drop. We think of humidity as how hot and sticky it is outside. The closer the water vapor pressure is to its saturation point, the more hot and sticky we feel. We associate humidity with heat since that is when we are uncomfortable, but rain is caused by the relative humidity rising to 100% because the humid air cooled to the point that the saturation pressure dipped below the current vapor pressure (or other pressure changes, or a combination of both). You can learn more at the link below. I hope this helps.

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.
The measurement of the amount of water vapor in the air compared to the amount needed for saturation at a specific temperature?
A measurement of how much water vapor is in the air at any particular place is called relative humidity. Relative humidity is measured with a psychrometer.
What does relative humidity measure?
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.
