If two soap bubbles of different radii are connected by a tube:;fn fofHkUu f= nks lkcqu ds cqycqyksa
Show answer and solution
The excess pressure inside the soap bubble in inversely
proportional to radius of soap bubble i.e. , r being the
radius of bubble. It follows that pressure inside a smaller bubble is
greater than that inside a bigger bubble. Thus, if these two bubbles are
connected by a tube, air will flow from smaller bubble to bigger bubble
and the bigger bubble grows at the expense of the smaller one.
