A soap bubble of radius R is blown. After heating the solution a second bubble of radius 2 R is blown. The work required to blow the second bubble in comparison to that required for the first bubble is
Text Solution
Verified by ExpertsThe correct answer is:
C
Work done to form a bubble of radius R
Work done to form a bubble of radius 2R
∴ ∴ 
If surface tension of soap solution is same then
But in the problem temperature of solution is increased so its surface tension decreases.
∴ ∴
