Vedclass · Answer

(C) The excess pressure inside a soap bubble of radius $r$ is given by $P = \frac{4T}{r}$, where $T$ is the surface tension of the soap solution.Since the pressure is inversely proportional to the radius $(P \propto \frac{1}{r})$, the smaller bubble has a higher internal pressure than the larger bubble.When connected by a tube, air flows from the region of higher pressure to the region of lower pressure.Therefore, air flows from the smaller bubble to the larger bubble.

If two soap bubbles of different radii are connected by a tube, then
