Relative humidity
Atmospheric air is a mixture of gases composed mainly of nitrogen (78%), oxygen (21%) and water in vapor form, in a variable percentage.
The relative humidity (RH) is the ratio between the amount of water vapor contained in an air mass and the maximum amount of water vapor that the same mass of air is able to contain at the same conditions of temperature and pressure .
The relative humidity is measured in percentage. If the relative humidity is 100% it means that the mass of air contains the maximum amount of water vapor in those conditions . The air with a relative humidity of 100% is called saturated .
If we speak about relative humidity of 50%, it means that the air contains half of the maximum amount of water vapor that could hold at that temperature.
If we put water vapor in a saturated air mass (relative humidity 100%), this condensates (liquefies) precipitating in the form of droplets.
