Question

Explain, why dogs pant during hot summer days using the concept of evaporation?

Answer 1

Answer:

Dogs pant to cool themselves.

Explanation:

Dogs cannot sweat through their skin to cool themselves down. They can sweat through their paws and tongue only. So, during hot summers, they pant. The tongues of dogs have a wide surface area, and the evaporation of water molecules from the tongue produces a cooling effect.
