Why doesnt air pressure crush objects?
There is air pressure on all sides, inside or outside. The air pressure pushes on the object all ways and nothing falls. If you only apply pressure on the bottom then the object will lift. If you apply pressure on the top, the object will collapse. If air pressure is pushing side ways, the object will move sideways.
Why does the pressure decreases when you are in a high mountain or in the peak of the mountain?
Air pressure is the weight of the air above you. When you ascend to some altitude above the Earth's surface, part of the air is beneath you, so the weight of the air above you, and therefor the pressure where you are, is reduced. Exactly the same reason that the pressure on the football player in the middle of the pile-up is less than the pressure on the guy with the ball, at the bottom of the pile.
Weight of air pressing down?
Air pressure.
If there is pressure on the inside and outside of a plastic bottle what is causing the force?
All liquids and and gases have pressure. Pressure is also a force but does not depend on area it acts. Pressure is arising from its own weight. The molecules in liquids and solids areattracted downward due to earth's mass(gravitational force). The impact of this gravitational force per unit area is the pressure. if there is a liquid or gas there must be pressure. the magnitude of pressure inside a plastic bottle depends on the weight of the air in it.
The force of air pushing down?
You might have expected the result to be pressure, but it's not. Pressure occurs due to the bombardment of air molecules on a surface. The weight of a column of air causes so little pressure that it can be considered negligible.
Why is the pressure in a pressure chamber dfferent at the top and bottom?
At the bottom, there is the additional weight of the gas or liquid above the surface level.
Why is pressure greater at the bottom of the pool rather than the top of the pool?
more water is on top of it putting more weight on the water at the bottom
Why do dams need to be thicker on the bottom and thiner at the top?
because the water pressure on the damn is much higher on the bottom of it than the top.
How does height affect fluid pressure?
As the depth of a fluid column increases, the pressure at the bottom increases due to the weight of the additional material above.j3h.
Why liquid storage tanks are made thick near the bottom?
Because weight exerts pressure as it 'accumulates'. There is little weight at the top of the container, but as gravity attracts the liquid towards the bottom of the container, so the pressure is greatest there. Put some water into a balloon and see where the pressure of the water pushes on the skin of the balloon.
Would the pressure be greater at the top of a mountain or at the bottom of it?
At the bottom. You can think of the air pressure at a given location as being the weight of all the air in a column above it. Thus, the higher you go, the less air there is above you, and thus the lower the air pressure. In the extreme, when you rise out of the athmosphere, there is no air above you at all, and the air pressure is effectively zero - a vacuum. Air pressure is greater at the bottom of a mountain.
Does the bottom surface of a submarine experience the same hydrostatic pressure as the top surface?
No, it will be greater Imagine pressure as the weight of a column of water over an area, typically one sq. in. So the deeper you go, the greater the weight, the greater the pressure.
Why are dams over rivers are made broader at bottom than at the top?
The pressure of the water (the weight) is greater at the bottom, due to the depth of the water. As the pressure is less near the top, the top of the dam wall doesn't need to be as thick as the bottom of the dam wall.
What would the pressure be in a liquid contained in a vertical tube sealed at the top with a submerged open bottom be?
It would be the same as the pressure in the liquid outside the tube at the open end- the deeper it is in the liquid, the higher the pressure.
Why does air exert pressure?
Air exerts pressure in the same way that water exerts pressure on a diver. Air has weight, and because we are at the bottom of a blanket of air that surrounds the earth, the weight of that air is pressing down on us (creating pressure). If you go under water, you'll feel the additional pressure created by the weight of the water above you.
Why are dams made thinner at the bottom?
This is because the pressure in a liquid increases with depth. This means that the pressure at the bottom of the dam is more. Hence it is more liable to break out from the dam as more pressure is exerted on the walls. So, the walls are thicker at the bottom.
Why is your tire always flat at the bottom?
Your TIRE, has hundreds of pounds of weight and pressure, and the tire is made of flexible material. It will be a little flat when stationary, or in motion. Just like feet; the pressure flattens temporarily with pressure applied.
