Byju's Answer. Question 1 Why does a desert cooler cool better on a hot dry day? Open in App. When a liquid evaporates, the particles of the liquid absorb energy from the surroundings to compensate for the loss of energy during evaporation. Since evaporation causes cooling, this makes the surroundings cool. In a desert cooler, the water inside it is made to evaporate. This leads to absorption of energy from the surroundings, thereby cooling the surroundings.

Why does a desert cooler cool better on a hot

Evaporative cooling is a natural and energy-efficient cooling process that uses the evaporation of water to lower the temperature of the surrounding air. It works on the principle that when water evaporates, it absorbs heat from the air, resulting in a cooling effect. In an evaporative cooling system, a fan draws warm outside air through moistened pads or media, where the water evaporates, cooling the air. This evaporation process requires heat, which is absorbed from the surrounding air molecules, resulting in a drop in temperature.
