Why does a desert cooler cool better on a hot dry day??
Please give me a some thanks..
Good morning friends..

Answer:
On a hot dry day, the humidity will be low and the temperature will be high. The temperature of the air will be relatively higher and energy transferred will be more. Since the same volume of air will be circulated energy transferred per given volume of air will be more on a hot day. Evaporation will be faster resulting in better cooling. On a dry day, water vapor present in the air will be less, and the circulation of this air will provide faster cooling compared to a humid day. Humid air contains more water vapor content so energy transferred will be less and the rate of cooling will be less. Therefore desert cooler cools better on a hot dry day.

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.
