If two soap bubbles of different diameters are brought in contact with each other through a tube, what will happen?
When two soap bubbles of different diameters are brought in contact through a tube, they will adjust their sizes due to surface tension. The smaller bubble will grow larger, and the larger bubble will shrink to achieve equilibrium until they reach the same size.

When two soap bubbles of different diameters are brought in contact through a tube, they will adjust their sizes due to surface tension (option C). Surface tension causes the pressure inside the bubbles to equalize, leading to the transfer of air from the larger bubble to the smaller one. As a result, the smaller bubble will grow larger, and the larger bubble will shrink until they achieve equilibrium and reach the same size. This phenomenon occurs because smaller bubbles have higher internal pressure compared to larger bubbles of the same surface tension. Therefore, the interaction between the bubbles through the connecting tube allows them to redistribute air and adjust their sizes accordingly, demonstrating the principle of surface tension and pressure equilibrium in soap bubbles. Unlike options A, B, or D, which do not accurately describe the process of bubble interaction, option C reflects the dynamic adjustment of bubble sizes to achieve equilibrium through surface tension effects.
