Question

Why does a desert cooler cool better on a hot dry day?
Please answer, I will mark you as brainliest.

Answer 1

Answer:

Evaporation depends on the amount of water vapour present in air (humidity). ... On a hot dry day, the amount of water vapour present in air is less. Thus, water present inside the desert cooler evaporates more, thereby cooling the surroundings more. That is why a desert cooler cools better on a hot dry day.
