Question

Q1. Why does a desert cooler cool better on a hot dry day?​

Answer 1

Answer:

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.

Hope this answer is helpful . Have a great day ahead.

Answer 2

The water when evaporated from a desert cooler absorbs energy from the surrounding for compensating the loss of energy during evaporation making the surrounding cool.

Evaporation is inversely proportional to humidity. So on a hot dry day, the evaporation is more so the surrounding is more cooled.
