The valve V in the bent tube is initially kept closed. Two soap bubble...
Explanation:
When valve V in the bent tube is initially kept closed, two soap bubbles A (smaller) and B (larger) are formed at the two open ends of the tube. When V is opened, air can flow freely between the bubbles. The size of the bubbles will change due to various factors.
- Surface Tension: Surface tension acts to minimize the surface area of the bubble. The pressure inside the bubble is higher than atmospheric pressure, which causes the bubble to expand. The larger the bubble, the more surface area it has, and the more surface tension acts to reduce its size. Smaller bubbles have less surface area, so surface tension has less of an effect on them.
- Gas Pressure: The pressure inside the bubble is determined by the amount of gas it contains. As air flows from one bubble to the other, the pressure inside each bubble will change. If one bubble has more gas than the other, it will have a higher pressure and will tend to expand.
- Volume: The volume of each bubble will change as air flows between them. If the smaller bubble has a smaller volume, it will tend to compress as air flows into it from the larger bubble. The larger bubble will tend to expand as air flows out of it into the smaller bubble.
Based on these factors, we can conclude that:
- Option A is incorrect because the size of the bubbles will change due to the factors mentioned above.
- Option B is incorrect because the bubbles will not necessarily become of equal size. The size of each bubble will depend on its initial size, the amount of gas it contains, and the volume of the other bubble.
- Option D is incorrect because the sizes of the bubbles will not become interchanged. The larger bubble will tend to expand, and the smaller bubble will tend to compress.
- Option C is correct because the smaller bubble will tend to compress as air flows into it from the larger bubble. The larger bubble will tend to expand as air flows out of it into the smaller bubble. This will cause A to become smaller and B to become larger.
