Question

38. The water at the bottom of a pond remains cool
in summers. It is due to
(a) Evaportion process
(b) Radiation process
(c) Conduction process
(d) Convection process​

Answer 1

Answer:

Evaporation cause cooling  therefore in summer when water evaporates from the surface of the pond it causes cooling of the water. Therefore a) Evaportion process is your answer ...

Explanation:

Please mark me as brainliest

Answer 2

Explanation:

heat energy of water molecules is transferred to the surface water molecules i. e. the water molecules on the top of pond water gets all the heat energy,

The surface molecules of water then evaporate taking latent heat of vapourisation and thus cooling the water

Hence , ans= a) evaporation
