Evaporation because it requires 2,260 Joules to gain heat energy. Condensation, freezing, and melting require less Joules than evaporation.
Almost all energy conversions involve a loss of energy.
Water molecules gain energy in order to vaporize. That additional energy is needed in order for the water molecules to overcome the attraction that they have for the other water molecules in the liquid that they are part of. In the gas phase, water molecules move independently of each other and are not connected as they are in the liquid state.
Vaporatization gains energy because it is the opposite of evaporation and evaporation loses energy. Here are some other things that, like vaporation, gain energy: -melting ... ... ... ... wait one minute, let me think again... oh ya now i remember... -nothing else :D
These are exact opposities - heat gain is an increase in energy that results in an increased temperature of the material. Heat loss is a loss in energy that results in a decreased temperature of the material.
For what?It requires a heat gain for the water,but a heat loss for whatever the water is in contact with.
A temperature change requires as gain or loss of heat energy.

Water gains energy in evaporation to become water vapour.

On a long term an equilibrium exist.
These are exact opposities - heat gain is an increase in energy that results in an increased temperature of the material. Heat loss is a loss in energy that results in a decreased temperature of the material.
Some molecules from the surface of the liquid gain more energy and are able to escape in the atmosphere.
evaporation, or boiling if the temp. is high enough
this is because you have to maintaion the core body tempreture
