MHT CET Physics question
The work done in blowing a soap bubble of radius 'R' is 'W₁' at room temperature. Now, the soap solution is heated. From the heated solution another soap bubble of radius '2R' is blown and the work done is 'W₂'. Then [MHTCET 2023]
Answer: (C)
Solution
Work in blowing a bubble is (two surfaces), so for radius 2R it would be at the same T; heating lowers the surface tension, so ; (a) is
