Question

(b) Relative humidity and absolute
humidity

difference between​

Answer 1

Absolute humidity is the measure of water vapor (moisture) in the air, regardless of temperature. ... 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) .

$\LARGE{ \underline{\underline{\sf{Humidity:}}}}$

The water content in. the atmosphere is called humidity.
