66The smaller bubble keeps on getting smaller and the bigger one keeps getting bigger as the air flows from the smaller to larger due to higher pressure within the smaller bubble.
Two bubbles (same liquid) of radius r and R (R>r) are connected by tube of negligible volume. The tube has a valve. When the valve is opened, what will happen to the sizes of the bubbles. (qualitative and not quantitative i.e no numerical calculations required)
