Relative Humidity (%RH)
Relative humidity (%RH) is the degree of saturation - or the amount of vapour in the air - relative to the amount that it would hold if it were saturated. Relative Humidity is often expressed as a
percentage; air saturated at a given temperature at 100%RH.
If the air is heated up, the amount of water vapour that it can hold when saturated increases. Therefore, the %RH decreases, even though the real amount of water remains constant. Similarly, if air
is cooled down, the amount of water vapour that it can hold decreases. Therefore, its %RH increases. The condensate forms when there is a excess of water in saturated air .
