Vedclass · Answer

(C) The excess pressure inside a soap bubble of radius $R$ is given by $\Delta P = \frac{4T}{R}$,where $T$ is the surface tension of the soap solution.Since $\Delta P \propto \frac{1}{R}$,the smaller bubble has a higher excess pressure compared to the larger bubble.When the two bubbles are 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,causing the smaller bubble to shrink and the larger bubble to grow.
