Hello..... ☺
The fastest moving molecules
(with 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.
<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.
thank you ☺

¤ Evaporation is the phenomenon of change of a liquid into vapour at a temperature below its boiling point.
=>The process occurs only at the surface of a liquid.
=>The different particles of a substance possess different amounts of energy and many particles at the surface gain enough energy to overcome the forces of attraction present in the liquid and change into the vapour state.
Principle:
=>The Molecules with the highest kinetic energy or fastest moving molecules 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.
=>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.
=>Basically , evaporation occurs because systems seek equilibrium.
=>There is a low concentration of molecules in the air, and a high concentration in the liquid.
