Absolute humidity
The absolute humidity is the amount of water vapor contained in a kg of dry air.
It does not vary with temperature variations. It can increase only by adding more water vapor in the air, and can decrease only by removing water vapor from the air (dehumidification) .
For example, one kg of air at +20°C with 60% HR contains 8.77g of water vapor (absolute humidity).
If we cool the air bringing it to +15°C, it will reach 82.29% of relative humidity and 8.77 g/kg of absolute humidity. If we bringing it up to +50°C, relative humidity will be 11.35% and absolute humidity still 8.77 g/kg.
