The compressibility of water is very low.
you increase the pressure
The pressure will slightly increase.
If the stopper has an airtight seal, the pressure in the bottle will increase, with the same amount of air and water confined to a smaller area.
The pressure at the bottom of the bottle is the greatest. It decreases as the level comes up and is the least at the top.
Because your hand replaces the column of air which was 'pressing' on the content of the bottle. Your hand exerts more pressure than the air.(: :) :p P:
The narrowing will form a bottle-neck. The build-up of water held back will add weight and, therefore, increase the pressure at the narrowing. This will increase the water's speed as it emerges from the narrowing.
The pressure in the ocean would change the shape of a glass bottle. If the water pressure was high then it would squeeze the bottle until it shattered.
When water freezes it expands in the bottle, and if there is to much pressure on the sides of the bottle it breaks.
as water depth increases then so does the water pressure
No
If it is fresh water, and the surface is at sea level, then the pressure at the surface is 14.69 psi. As you submerge, then the pressure from the weight of the water above you is added to the air pressure above the water. For each foot that you descend, the water pressure will increase by 0.4331 psi, so at 328 feet deep, the water pressure is 142.0568 psi. Add the 14.69 psi air pressure to get 156.7468 psi.
Nothing can be done to increase the level of underground water. That is an entirely natural situation.Nothing can be done to increase the level of underground water. That is an entirely natural situation.
