What is the amount of water vapor in the air compared to the amount of water vapor for saturation at a certain temperature?

What is the amount of water vapor in the air compared to the amount of water vapor for saturation at a certain temperature?

Relative humidity
Relative humidity, RH, is the ratio of the amount of water vapor present in the air to the maximum amount of water vapor needed for saturation at a certain pressure and temperature. It is typically multiplied by 100 and expressed as a percent.

What term defines the ratio of the amount of water vapor actually in the air to the amount of water vapor that the air can hold at saturation?

The mass of water vapor in a given volume of air. It represents the density of water vapor in the air.

Which expression of humidity is defined as the amount of water vapor in the air as a percentage of the maximum amount the air can hold at a given temperature?

saturation
Relative humidity tells us how much water vapor is in the air compared with the maximum possible. At its maximum, denoted as saturation, the relative humidity is 100%, and evaporation is inhibited. The amount of water vapor the air can hold depends on its temperature.

What word best describes a measure of how much water vapor is in the air compared to how much it can potentially hold?

The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity.

Which air temperature can hold the greater amount of water vapor?

Hot air expands, and rises; cooled air contracts – gets denser – and sinks; and the ability of the air to hold water depends on its temperature. A given volume of air at 20°C (68°F) can hold twice the amount of water vapor than at 10°C (50°F).

What is it called when air contains the maximum amount of water vapor that it can hold?

When a volume of air at a given temperature holds the maximum amount of water vapour, the air is said to be saturated. Relative humidity is the water-vapour content of the air relative to its content at saturation.

What happens when RH reaches 100%?

When relative humidity reaches 100 percent or is saturated, moisture will condense, meaning the water vapor changes to liquid vapor. Dew Point is the temperature at which air reaches 100 percent relative humidity. If the air is cooled below dew point, moisture in the air condenses.

What is the term for the amount of water vapor in the air?

Humidity is a term where the amount of water vapor that is in the air. Humidity is blamed for that muggy, steam-room feeling you experience on certain summer days. What is the term for the amount of energy a chemical reaction needs?

How does relative humidity affect the temperature of water vapor?

Relative humidity is therm used in measuring the amount of water vapor in the air. High humidity can make the temperature feel higher than what the actual temperature is. What term is defined as the amount of water vapor in the air compared to the amount it could hold at a given temperature? Humidity relative humidity How do you spell water vapor?

How is water vapor different from liquid vapor?

Humidity is the amount of water vapor in the air.Humidity indicates the likelihood of precipitation, dew, or fog. How is water vapor different from liquid vapor? There is no such thing as “liquid vapor.” This term contradicts itself. A vapor is a substance that is in its gaseous phase. What is the term for the amount of water in the atmosphere?

Which is the best description of relative humidity?

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 Wiki User 2014-05-06 13:06:52
