If two soap bubbles of different radii are connected by a tube, then
  • a)
    there is no flow of air
  • b)
    air flows from the smaller bubble to the bigger
  • c)
    air flows bigger bubble to the smaller bubble till sizs are interchanged
  • d)
    air flows from the bigger bubble to the smaller bubble till the sizes become equal
Correct answer is option 'B'. Can you explain this answer?

If two soap bubbles of different radii are connected by a tube, thena)...
Explanation:

When two soap bubbles of different radii are connected by a tube, air flows from the smaller bubble to the bigger bubble. This is due to the pressure difference between the two bubbles.

Pressure difference between the two bubbles:

The pressure inside a soap bubble is inversely proportional to its radius. So, the smaller bubble has a higher pressure compared to the bigger bubble. This pressure difference causes air to flow from the smaller bubble to the bigger bubble.

Flow of air:

The flow of air continues until the sizes of the two bubbles become equal. At this point, there is no pressure difference and hence no flow of air.

Conclusion:

Thus, option 'B' is the correct answer as air flows from the smaller bubble to the bigger bubble when two soap bubbles of different radii are connected by a tube.
