... is the mass of water vapour present in a given volume of air
... the mass of water in a given volume of air as a percentage of the mass required to saturate that given volume of air at the same temperature.
Thus,
From the ideal gas equation,
Maximum absolute humidity @ 0 C
= 4.8 mg/L
Maximum absolute humidity @ 20C
= 17 mg/L
Maximum absolute humidity @ 37C
= 44 mg/L
Absolute humidity doesn't change with temperature.
But,
Saturated absolute humidity varies with temperature
Thus,
Relative humidity also varies with temperature
