Can you please explain furtherjbriggs444 said:As I understand it, you have a bottle with an opening at the top and a valve on the opening.
You have added a small hole at the bottom (small enough so that air does not bubble in through it). You notice that when the top valve is open that the water flows freely out the bottom. But if you close the valve at the top, water no longer flows out.
If you leave the valve open at the top, does anything flow into the bottle through the opening?
If you close the valve, what happens to the air pressure in the bottle above the water if some water, hypothetically, continues to flow out the hole?
Can you answer either question?Einstein60 said:Can you please explain further

The movement of the water bottle is caused by a phenomenon known as Brownian motion. This is the random movement of particles suspended in a fluid, such as water molecules in the bottle. The constant collisions between these particles create a net force that causes the water bottle to move in a seemingly random manner.
The speed of the water bottle's movement is influenced by several factors, including the temperature of the surrounding environment and the viscosity of the fluid. Higher temperatures and lower viscosity will result in faster movement, while lower temperatures and higher viscosity will result in slower movement.
Yes, Brownian motion can be observed in any fluid, including liquids such as oil, alcohol, and even air. However, the movement may be more difficult to see in thicker or more viscous fluids.
The size and shape of the water bottle do not significantly affect the movement caused by Brownian motion. However, a larger bottle may be easier to observe, and a cylindrical shape may provide a more consistent movement compared to a bottle with irregular shapes.
Brownian motion is closely related to the concept of diffusion, which is the movement of particles from an area of high concentration to an area of low concentration. It is also related to the kinetic theory of matter, which explains the behavior of particles in a substance based on their motion and energy.
