What happens when two different radius bubbles are connected by a hollow tube?

∙ 15y ago
The larger bubble has a larger diameter and therefore less pressure than the smaller bubble since:
p(in) = p(out) + 2y/r.
p = pressure
y = surface tension
r = radius
Therefore, pressure is inversely proportionate to the radius size.
Since the smaller bubble has a smaller radius, and therefore, a greater internal pressure, it would "push" the air through the hollow tube to the larger one until the smaller one ceases to exist.
