The cooling by a desert Cooler is based on: (1) Hot air replacement (2) Air dehydration (3) Evaporative Cooling (4) Air Rehydration
by

1 Answer

Answer :

(3) Evaporative Cooling Explanation: Nature's most efficient means of cooling is through the evaporation of water. Desert coolers make use of evaporative cooling that works on the principle of heat absorption by moisture evaporation. As water is evaporated, energy is lost from the air, reducing the temperature. Thus, cooling effect is produced.
