Why does a desert cooler cool better on a hot dry day?
Asked by Topperlearning User | 05 Apr, 2016, 12:38: PM
Expert Answer
On a hot dry day, due to the increase in temperature, the rate of evaporation of water is more. Also the dryness of the air i.e. decrease in the humidity of the air increases the rate of evaporation. Therefore, a desert cooler cools better on a hot dry day.
