Question

Vapour content in air is measured using a physical quantity called .....

(A) Absolute Humidity

(B) Relative Humidity

(C) Dew point

(D) Humidity​

Answer 1

Vapour content in air is measured using a physical quantity, called Absolute Humidity.

Explanation:

• (A) Absolute Humidity: Absolute Humidity is the ratio of water vapour mass in a volume of moist air to this volume.
• (B) Relative Humidity: Relative Humidity is the ratio of partial pressure of water vapour to its equilibrium vapour pressure.
• (C) Dew point: The dew point is a calculating temperature with whose help, air has to be cooled to be saturated with water vapour.
• (D) Humidity: The concentration of water vapour in air is defined as Humidity.

Answer 2

The vapour content in air is measure by the absolute humidity.

• The vapour content is measure by two terms one is the absolute humidity and other is relative humidity.
• In the absolute humidity, the vapour content is measured without taking in the temperature dependency.
• But in the relative humidity, here the water content in air talking its percentage with the total amount of current temperature is at that time.
• The relative humidity is taken to check for the weather forcast,
