Amount of water vapour (gaseous) in a given volume of air (cubic metre) is known as:
A). Mixing ratio
B). Relative humidity
C). Absolute humidity
D). Specific humidity
Absolute humidity
The relative humidity of air at a given temperature is the ratio of mass of water vapour actually present in a certain volume of air to the mass of water vapour required to saturate the same volume of air at the same temperature, miltiplied by 100. Absolute Humidity refers to the amount of water vapour present in unit volume of air, expressed in grams per cubic metre.
