Evaporation is the process of liquid turning to gas at a temperature below its boiling point.
Principle of evaporation -
The fastest moving molecules (those with the highest kinetic energy) at the surface of the liquid have enough energy to break the attractive bonds with other molecules. They then escape the surface of the substance. Obviously, this only occurs with the molecules at the surface of the substance.
Since at higher temperatures the molecules have more kinetic energy, more of them are likely to escape, and so evaporation occurs more quickly at higher temperatures.
In general, evaporation occurs because systems seek equilibrium (there is a low concentration of molecules in the air, and a high concentration in the liquid).

Answer:
principle: evaporation is a surface phenomenon. The water molecules at the surface of a container tend to come out. So they gain heat energy from the nearby molecules and evaporates. As a result evaporation takes place.
