Question

Assertion A:bubble of soap is larger than the water
Assertion R: surface tension of soap bubble is less than that of water

(i)A is true but R is false
(ii)both A and R are true and R is the correct explanation of A
(iii)A is false and R is also false
(iiii)Both A and R are true R is not the correct explanation o A​

Answer 1

Answer:

answer is A. both assertion and reason crt and reason is crt explanation

Answer 2

Option 2 is correct as the surface tension of soap is less than water because of the presence of surfactants which makes the molecules loosely packed. So, assertion and reason both are true and it's explanation is correct

• Option (ii) is correct. Both A and R are true is the correct explanation of A.

• The reason is when soap is added to water, the surface tension gets reduced. This happens because surfactants are present in molecules of soap. The tension between the molecules get weaker. When it gets reduced, the surface tension helps the water stretching which results in more surface area and the bubbles get form.
• The assertion is additionally true since the surface weight is less than water due to surfactants that reduce the surface weight within the cleanser. The clarification is additionally practical, as the surface weight is lower than that of water. That's since surfactants have a lower premise surface tension than you'll discover in cleaning professionals.
