The Psychrometric Chart
The third property, dew-point temperature, is the temperature at which
moisture leaves the air and condenses on objects, just as dew forms on grass
and plant leaves.
When the dry-bulb, wet-bulb, and dew-point temperatures are the same, the air
is saturated. It can hold no more moisture. When air is at a saturated
condition, moisture entering the air displaces moisture within the air. The
displaced moisture leaves the air in the form of fine droplets. When this
condition occurs in nature, it is called fog.
