The rise of water in the dropper is due to atmospheric pressure.
When the bulb of a dropper is pressed, the pressure inside the dropper decreases and this causes the water to go inside the dropper.

Explanation:
Atmospheric Pressure:
- The rise of water in the dropper is due to atmospheric pressure.
- Atmospheric pressure is the force exerted by the weight of the air above us.
- When we press the bulb of the dropper, the air inside the dropper is compressed, creating a higher pressure inside the dropper compared to the outside atmospheric pressure.
- This higher pressure pushes the water out of the dropper.
Process:
- When the nozzle of the dropper is placed in the water and the bulb is pressed, the air inside the dropper escapes through the nozzle in the form of bubbles.
- The release of air reduces the pressure inside the dropper, allowing the atmospheric pressure to push the water into the dropper.
Key Points:
- The rise of water in the dropper is not due to the pressure of water or gravity of the earth.
- The shape of the rubber bulb simply helps in creating and releasing pressure when squeezed and released.
- It is the difference in pressure (higher inside the dropper and lower outside due to atmospheric pressure) that causes the water to rise in the dropper.
