1. Why does a desert cooler cool
better on a hot dry day?
2./ How does the water kept in an
earthen pot (matka) become cool
during summer?
​

Answer 1

Answer: The water kept in an earthen pot (matka) becomes cool during summer because of the evaporation of water through the fine holes in the earthen pot which makes it cool.

Answer 2

The particles of liquid in desert cooler absorb energy from the surrounding to regain the energy lost during evaporation. In summer this is fast. Hence desert cooler cool better in a hot dry day.
