Question: At the moment immediately after the experiment shown in the figure ends, the temperature of the wide-mouth bottle and the surrounding environment remains temporarily unchanged. A U-shaped glass tube containing a small amount of liquid is then used, with one end connected to the inside of the bottle and the other end open to the outside atmosphere. After the system is allowed to rest until it reaches a new equilibrium, which of the following is the most likely situation for the liquid levels in the U-tube?
A. The liquid level on the side open to the outside air is higher
B. The liquid level on the side connected to the bottle is higher
C. The levels on both sides remain equal, because the free surface of a static liquid must always be horizontal
D. The liquid levels will oscillate violently for a long time and cannot reach a stable height
Clues:
1. The top image shows an egg that is larger than the opening of a glass bottle and cannot pass through it.
2. The bottom image shows the egg has moved from the opening to the inside of the bottle.
3. In the bottom image, there is a crumpled, ashen-looking object at the bottom of the bottle, suggesting something was burned inside.
