Question

What do you mean by humidity? How can we express it?

Answer 1

Explanation:

Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. ... Relative humidity, expressed as a percentage, indicates a present state of absolute humidity relative to a maximum humidity given the same temperature

Answer 2

the actual amount of water vapour present in air is called humidity or absolute humidity. we express it in terms of relative humidity in perentage.

relative humidity is the ratio between the humidity in the air at a given temperature and the

maximum capacity of the air to hold moisture at that temperature.
