Question

why does a desert cooler cool better on a hot dry day?​

Answer 1

Answer:

a desert cooler cools better on a hotdry day as there is very less water vapour in atmosphere hence it is able to add more and morewater content to air so that when goes near your body evaporates and cools welll

Answer 2

Answer:

The cooling in a desert room cooler is caused by evaporation of water. A desert cooler cools better on a hot and dry day because the higher temperature on a hot day increases the rate of evaporation of water, and the dryness of air also increases the rate of evaporation of water. And due to increase the rate of evaporation of water, a desert room cooler cools better on a hot dry and day.
