When air's temperature rises due to heating, with no alteration to its moisture content, the process is termed sensible heating.
During sensible heating, the air's dry bulb temperature elevates, while its specific humidity (the mass of water vapor per unit mass of dry air) stays unchanged.
This phenomenon is observed in systems like heating and air conditioning during colder periods.
Humidification involves the addition of moisture to air.
Sensible cooling extracts heat, leaving humidity constant, but in reverse of heating – it cools the air.
Dehumidification is the reduction of moisture content.
Consequently, heating air without altering its specific humidity is accurately identified as sensible heating.
