If two soap bubbles of different radii are connected by a tube,
air flows from the bigger bubble to the smaller bubble till the sizes become equal
air flows from bigger bubble to the smaller bubble till the sizes are interchanged
air flows from the smaller bubble to the bigger
there is no flow of air.
As we learnt in
Pressure Difference in Water Droplet -
- wherein
T- Temperature,
R- Radius
We know that
Air will flow from smaller bubble to bigger bubble and the bigger bubble grevs at the expense of the smaller one.
Correct option is 3.
Option 1)
air flows from the bigger bubble to the smaller bubble till the sizes become equal

Option 2)
air flows from bigger bubble to the smaller bubble till the sizes are interchanged
This is an incorrect option.
Option 3)
air flows from the smaller bubble to the bigger
This is the correct option.
