Question

difference between relative humidity and absolute humidity​

Answer 1

Absolute humidity is the measure of water vapor (moisture) in the air, regardless of temperature. It is expressed as grams of moisture per cubic meter of air (g/m3). Relative humidity also measures water vapor but RELATIVE to the temperature of the air.

Answer 2

$\LARGE{ \underline{\underline{\sf{Relative\: humidity:}}}}$

The ratio between the amount of water vapour present in the atmosphere and the total water holding capacity of the atmosphere at a given temperature is called relative humidity . It is usually expressed in percentage . If the absolute humidity is half of the total water holding capacity at a particular temperature , then the realtive humidity will be 50%. It is measured using an instrument called wet and dry bulb thermometer .

$\LARGE{ \underline{\underline{\sf{Absolute\: humidity:}}}}$

The actual amount of water vapour present in the atmosphere is called absolute humidity . It is measured as the amount of water vapour present per cubic metre volume of air (g/m³) .
