Question

Relative humidity is :

• A. The relative mass of water vapour per unit volume of space
• B. The mass of water vapour per unit mass of moist air
• C. The percentage ratio of the amount of moisture in a given space to the amount which that volume could contain if it were saturated
• D. The humidity at which air becomes saturated cooled under constant pressure and with constant water vapour content

Answer 1

The correct option is C The percentage ratio of the amount of moisture in a given space to the amount which that volume could contain if it were saturated

The amount of water vapour present in air represented as a percentage of the amount method for saturation of the same temperature
