Evaporative cooling happens when a liquid evaporates and the one that stays behind has a cooling effect.
This process occurs when hot molecules possessing immense amount of kinetic energy change into gaseous state.
Examples:
Evaporation of water from mud pots,
Acetone present in nail paint remover absorbs heat from our body and evaporates,
Evaporating of sweat keeps body cool
