Question
If two soap bubbles of different radii are connected by a tube,
Options
A.air flows from the bigger bubble to the smaller bubble till the sizes are interchanged.
B.air flows from bigger bubble to the smaller bubble till the sizes are interchanged
C.air flows from the smaller bubble to the bigger.
D.there is no flow of air.
Solution
The pressure inside the smaller bubble will be more 
Therefore, if the bubbles are connected by a tube, the air will flow from smaller bubble to the bigger.
Therefore, if the bubbles are connected by a tube, the air will flow from smaller bubble to the bigger.
