Why does air exert pressure?

Answer . 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 (MORE)

What is air pressure or atmospheric pressure?

air pressure is mainly of two types high pressure and low pressuring speed of air increase over a surface , a low pressure is created. . which was discovered by Daniel Bernoulli it was called the Bernoulli's principle

Which atmospheric layer has the greatest air pressure?

It's the troposphere because : The troposphere contains 75 per cent of the atmosphere's gas. It also holds huge amounts of dust and water vapor, and is often dense with clouds and mist. Air pressure is greatest in the troposphere, because gravity pulls the atmosphere towards the Earth, squeezing mo (MORE)

Does air exert pressure?

Yes. All gases exert some pressure due to the weight of their molecules. But it depends on the concentration of the gas (mass per volume) and will vary with temperature and flow velocity. In the atmosphere, air pressure is created by gravity, which pulls down on the molecules at the surface and th (MORE)

How can you prove that the atmosphere exerts pressure?

The original experiment that demonstrated this was a portable mercury column. If you have a large bowl full of Mercury (a liquid metal) and a 1 meter long glass tube open at one end, then you can make a simple barometer. First, completely fill the tube with mercury, and temporarily close of the o (MORE)

What atmospheric layer has the lowest pressure?

http://www.windows.ucar.edu/tour/link=/earth/Atmosphere/layers.html Exosphere That's the outer most layer in the atmosphere. It experiences very low pressures due to the weak gravity at such astronomically high altitudes, and thus the more massive and heavy gases are in levels of the atmosphere, (MORE)

What are the Experiences of air exerts pressure?

1. Filling a test tube with water and putting a piece of plastic on it and turning it upside down.(the water does not come out). 1.means that there is a pressure holding the water in the tube so two proves. 2. Putting in air in a syringe and putting a cap on the end, later holding the cap in placege (MORE)

Does cold air exert more pressure?

It depends on the situation. In a contained vessel (eg a tyre), then hot air would exert a higher pressure. In general outside the pressure is (fairly) constant, and it is the density which changes with temperature. Imagine if this weren't true; you could have two pockets of air next to each othe (MORE)

How can you prove that air exerts pressure?

If you evacuate all the air between 2 pieces of glass, the glass is pressed together by atmospheric pressure from the outside. By measuring the force needed to separate the panes of glass, one can extrapolate the pressure exerted on the glass.

What direction does air exert pressure?

All directions, just like water when you are diving. That is why chocolate-covered cream cakes (and a lot of other stuff) stay together at atmospheric air pressures, but will explode in vacuum, or why water will boil at lower temperatures on high mountains.

Does air exerts pressure?

The simple answer is yes. But ... ... Pressure = 1/volume Hence to allow pressure =0, volume must be infinitely large. Say for example in outer space.

Which layer of the earth's atmosphere has the highest air pressure?

The troposphere is the layer of the earth's atmosphere with the highest air pressure. This is because the troposphere is the layer closest to the Earth's surface. As a result, the air is quite dense in the troposphere. As pressure is directly proportional to density, it means that the atmospheric pr (MORE)

Does moving air exert pressure?

air is like water--meaning that it's fluid.. and, like water, air exerts pressure when it is moving (and in any direction, too).

How will you show that air exerts pressure?

A large syringe or a bicycle pump is the best way. Place and hold a ball over the end of a large syringe, depress the plunger and let go of the ball You can put an empty soda bottle in your mouth and suck out the air. The outside air exerts pressure, collapsing the bottle.

An experiment on air exerts pressure?

As we know air is everywhere and we can't survive without air. It consists of various gases, dust particles, water vapors, etc. Air exerts a particular pressure on every single thing. Air pressure is calculated with the help of an instrument called barometer and according to it, the Earth's atmosphe (MORE)

What is the relationship between temperature air pressure and density in the layers of the earth's atmosphere?

With increasing altitude in the atmosphere, pressure decreases andso does density. Temperature varies depending on the layer in whichthe air is. The top of the stratosphere can be -50 degrees C, aswhere the thermosphere can be well over 500 degrees C. At ground level (0 feet above sea level) we con (MORE)

What are the earths eight layers of atmosphere?

The most widely used analysis of Earth's atmosphere is into five layers. From the surface of the planet out into space, they are: Troposphere - from the surface to between 7 and 17 km (depending on latitude) Stratosphere - Tropospheric boundary to about 50 km Mesosphere - ~50 km to ~85 km Ther (MORE)

Is the atmosphere a layer of air?

Not as much "a" layer of air as it is "the" layer of air. The atmosphere is the four major regions of air: Troposphere, Stratosphere, Mesosphere, Thermosphere

How air exerts pressure?

Here we consider a system as an open system .Now air forms the remaining system lwhich occupies remaining volume .;the considered system being small with respect to the volume enclosed by air ,there exists force exerted by air on this system in order to cover up the entire volume.----this is nothing (MORE)

Why are you not crushed by the huge pressure exerted by the atmosphere?

Because our bodies exert counter pressure and prevents it from bursting. Because the pressure inside your body is the same and cancels it out. The entire human body, including all the bones, tubes, sacks, and fluids in it, is constructed to develop an outward pressure that compensates for the (MORE)

Why is atmospheric pressure exerted in all directions?

Air expands to the container it is in. The container the air is in is the atmosphere. The air expands evenly in the container, so the pressure is applied evenly. However, because of the weight of air, more pressure is applied when closer to the ground then when higher up.

Why does atmosphere exert pressure on earth?

The atmosphere is made up of gasses. Gasses are physical substances, and all physical substance has weight. The atmosphere is 25 miles thick, and that 25 miles thick layer of gasses presses down on earth with a weight of 15 lbs. per square inch. That's how atmosphere exerts pressure on the earth.

What is the force that air exerts on earth?

That's the weight of the air. If you were to divide the total weight of the atmosphere by the Earth's total surface area, the quotient would be the atmospheric pressure at the surface.

Why is there more air pressure in the first layer of atmosphere?

The atmosphere consists of 5 layers: the troposphere, which we live in; followed by stratosphere, mesosphere, thermosphere and exosphere. Air pressure at any of these layers is typically caused by hydrostatic pressure, defined as P = hpg, where P is the pressure, h is the height or depth of fluid, a (MORE)

What is the air pressure of space in comparison to atmospheric pressure on earth?

We are so used to our atmospheric pressure down here on earth that we tend to think of it as the absolute norm; more often we don't think of it at all. The truth is that zero pressure, the theoretical pressure in deep space, or very close to it, is the situation in vastly more of the universe's volu (MORE)
