If a soap bubble expands, the pressure inside the bubble

  1. A
    Decreases
  2. B
    Increases
  3. C
    Remains the same
  4. D
    Is equal to the atmospheric pressure
View written solutionFree

Correct answer: A

Excess pressure inside the bubble $$ = \Delta P - {{4T} \over R}$$

$${P_{in}} = {P_{out}} + {{4T} \over R}$$

as 'R' increases 'P' decreases
