IT is evaporation.
Evaporation : This the phase transition from liquid state to
gaseous state, when it occurs at a termperature below the boiling point
of liquid (at a given pressure). As opposed to this, Boiling is the
process when vaporisation occurs at temperatures above the boiling
Condensation: when a material transforms into a liquid
form from gaseous form. The opposite of evaporation or vaporisation.
The gas is cooled in order to condense. WHen a gas/vapor meets a surface
wall and transforms into liquid, it is also callled condensation.
this is same as sweating in human bodies (called perspiration). same
process in plants/trees also. Transpiration is the word used for
plants. It is the evaporation of fluids (water) from under the skin
surface through vents. During this process, the fluid takes energy from
the body to transform into vapor. So it cools the body
