Question

What would be the absolute humidity of air if 1 cu. m. air contains 4.08 gms of vapour at 0°C temperature? 

Answer 1

Absolute humidity is defined as “the amount of water vapour in 1 cu.m. of air.”

Given, water vapour = 4.08 gms

The volume of air = 1 cu. m.

Thus, absolute humidity ${\displaystyle =\frac{\text{Mass of water vapour}}{\text{Volume of air}}}$

                                        ${\displaystyle =\frac{4.08}{1}}$

                                        = 4.08 gm/m³
