Why does a desert cooler cools better on a hot dry day?
Asked by Topperlearning User | 17 May, 2016, 01:28: PM
Expert Answer
On a hot day, due to increase in temperature, the rate of evaporation of water is high. Also, the dryness of the air, i.e, decrease in humidity of the air increases the rate of evaporation. Therefore, a desert cooler cools better on a hot dry day.
