Question

Two soap bubbles of different radii are formed at the two ends of a hollow tube. Initially, a valve in the middle of the tube separates the air in the two halves of the tube. When the valve is opened, then, 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 their sizes are interchanged, air flows from the smaller bubble to the larger bubble, there is no flow of air

MARKS App · Accepted Answer

P = 2 T R R , for the smaller bubble is less as compared to the larger one. Thus, pressure P will be more in the smaller bubble. Since air flows from higher pressure to lower pressure, therefore, here air will flow from smaller bubble to the larger bubble.
