What is ahsolute humidity?
 A The temperature to which humid air must be cooled at constant pressure to become statured. B The actual amount of the water vapor in a mixture of air and water. C The ratio of the water vapor actually present in the atmosphere to the amount that would be present if the air were saturated at the prevailing tempernture and pressure D None of the above
Explanation:

Detailed explanation-1: -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. This amount of space in air that can hold water changes depending on the temperature and pressure.

Detailed explanation-2: -Absolute humidity (expressed as grams of water vapor per cubic meter volume of air) is a measure of the actual amount of water vapor (moisture) in the air, regardless of the air’s temperature. The higher the amount of water vapor, the higher the absolute humidity.

Detailed explanation-3: -Absolute humidity is the total amount of water vapor present in the air. In other words, the weight of water vapor per volume of air is referred to as the absolute humidity. It is usually expressed as grams of water vapor per cubic meter of air.

Detailed explanation-4: -Solution: Absolute humidity is defined as the actual amount of water vapour which is present in the atmosphere. Absolute humidity= [Total amount of water vapour (in grams)]/ [Volume of air (in m3)]

Detailed explanation-5: -Absolute humidity: Its unit is grams of water vapor per cubic meter volume of air. It is a measure of the actual amount of water vapor in the air, regardless of the air’s temperature.
