Question

Assertion : It is easier to spray water in which some soap is dissolved.
Reason : Soap is easier to spread.

✓

Answer

(c) When a liquid is sprayed, the surface area of the liquid increases. Therefore, work has to be done in spraying the liquid, which is directly proportional to the surface tension.Because on adding soap, surface tension of water decreases, the spraying of water becomes easy.
