Solution

Evaporation is a process in which particles on the surface of any liquid gain energy from the surroundings.
After gaining energy, they will start moving with greater energy.
When they will gain enough energy to leave the surface, they will be converted into gas.
Therefore, the process where only the exposed surface of the liquid changes to gas is called evaporation.
