== Introduction ==
 
Air is a mixture of gases. The main components are summarized in table 1. In addition to these components, the air always contains a small amount of water, which exists in three states of matter:
*solid: ice, hail, snow
*liquid: rain, fog, dew
*gas: water vapor

Water is the only gas in the atmosphere that is present in its three states of matter. For the building trade, this leads to some undesirable phenomena such as condensation, corrosion and frost.
In addition to temperature, humidity is the main indicator for describing the climate. Relative humidity, for example, influences our wellbeing to a great extent.
