Explanation:

When we press the bulb of a dropper with its nozzle kept in water, air in the dropper is seen to escape in the form of bubbles. This happens because of the pressure applied on the bulb. Once we release the pressure on the bulb, water gets filled in the dropper because of the following reasons:

Atmospheric pressure: Atmospheric pressure is the force exerted by the weight of air on the earth's surface. When we press the bulb, the air inside the dropper is compressed and is at a higher pressure than the atmospheric pressure. When we release the pressure, the air inside the dropper expands and the pressure inside becomes lower than the atmospheric pressure. Hence, water is forced to enter the dropper due to the difference in pressure inside and outside the dropper.

Gravity of the earth: Gravity is the force that pulls objects towards the center of the earth. The dropper is filled with water because of the force of gravity. As the air is removed from the dropper, the water takes its place due to the force of gravity.

Shape of rubber bulb: The shape of the rubber bulb also plays a role in the filling of water in the dropper. The bulb is designed in such a way that when we squeeze it, the air inside the dropper is compressed and the pressure is increased. When we release the pressure, the bulb returns to its original shape, and the pressure inside the dropper decreases. This creates a vacuum in the dropper, and the water rushes in to fill the space created.

Therefore, the rise of water in the dropper is due to atmospheric pressure, gravity of the earth, and the shape of the rubber bulb.
