How does a syringe use atmospheric pressure?
Oh, dude, it's like this: when you pull back the plunger on a syringe, you decrease the pressure inside, creating a pressure difference with the atmosphere. So, the higher pressure outside pushes the liquid or medication into the syringe. It's basically like nature's way of helping you get that flu shot without even thinking about it.
What happens when you put rubber in liquid nitrogen?
the end of the wet stick freezes immediately. liquid nitrogen is very cold ( -196 degrees F)
Where is air pressure the greatest in the atmosphere?
Air pressure is the amount of force exerted on an object by the atmosphere. It is greatest at sea level.It is greatest in the exosphere, due to the fact that air pressure is greater as the altitude rises; the exosphere is the highest level within the atmosphere.Air pressure is greatest in the areas that are small and enclosed. This is because there is no way to escape.
How does air pressure vary with elevation?
The pressure of the air on one square-inch of your head is the weight of air from that square-inch all the way up to the top of the atmosphere. As you go up in elevation, some of the atmosphere is below you, and there is less of it above you. So the weight on each square inch, and thus the air pressure, becomes less.
How could pressure difference in earths atmosphere contribute to winds?
The pressure difference works this way. You literally have more air molecules in a given area, a "high" pressure front. The air wants to reach equilibrium, so it flows to a "low" pressure, or less air molecules in the same given area, front. What you feel is air molecules moving from one area to another, or wind.
Why atmospheric pressure varies with height in a different way from the way liquid pressure varies with depth.?
For the same reason. The liquid above the location considered, or the atmosphere above the position considered, helps contribute to the pressure; if there is more liquid or atmosphere above, there is more pressure.
What are the pressure measuring instruments?
a common manometer is a u-tube with a liquid filled about half way in each leg, one end is open to the atmosphere and the other connected to the thing that your measuring the pressure of, as the pressure increases, the liquid in the leg attached to your pressure of interest is forced down, and the pressure in the other leg is pushed up, because you are comparing it to the atmosphere it is a gauge pressure in comparison to the atmosphere =] hope this helps.
How does a straw work?
As you create a partial vacuum in the top part of the straw, the weight of the entire atmosphere above the glass applies a pressure of 15 PSI on the liquid surface. This pressure pushes the liquid up the straw until the pressure in the straw returns to 15 PSI too. If you keep creating the partial vacuum the air pressure will push the liquid all the way to the top of the straw and out.
What is in liquid?
The question is a bit vague, but two things come into play for pressure in a liquid: external pressure and hydrostatic pressure. For a liquid where the top surface is in contact with a gas, like a glass of water sitting out on the table, the external pressure would be the pressure of the gas. For the glass of water in this example, the pressure of the gas is just the ambient atmospheric pressure. In a pressure cooker with hot gas and hot liquid confined in a fixed volume, the pressure of the gas will probably reach the pressure the relief valve is set to. Hydrostatic pressure comes from the weight of the liquid above the liquid at any point in the liquid. As an example, if you go 10 meters down under the surface of the water in a swimming pool, you will feel the pressure created by the weight of the water above you. As a formula, P.H. (hydrostatic pressure) = (gravitational acceleration)x(density of liquid)x(depth of liquid). To get total pressure at any point in a liquid, you add the external pressure and the hydrostatic pressure. In situations like a hydraulic line, you would add the pressure exerted by the piston (external pressure) to the hydrostatic pressure from changes in the height of the hydraulic line. By the way, if the line goes UP, the effective depth is NEGATIVE and the hydrostatic pressure term is also negative, so you would have less pressure at the top of the hydraulic line than you did down at the level of the piston.

What is the relation between pressure in atmosphere and pressure?
Atmospheric pressure is the surrounding pressure around us. We live in the atmosphere and treat the atmospheric pressure as the base pressure. A pressure gauge would read 0 at atmospheric pressure. When we define the pressure in scientific way of absolute pressure, we need to add up an atmospheric pressure to the measured pressure.
What is the characteristic of atmosphere?
I think the atmosphere characteristic is how it is. by:Yoshi R. Walker * clear, can see though it often all the way into space * pressure, pressure reduces the higher you get * weather * temperature * carries materials such as dust, microbes long distances

Does Jupiter have layers?
Neptune (and the other gas giants) have layers, but not in the way you might imagine. The planet is thought to have a three-layer structure. It consists of an inner rocky core, with a middle ice-like layer of fluid which is probably liquid diamond. Carbon condenses from the abundant methane on Neptune and because of the immense pressure, density, and temperature that exists deep within the gas giant, the carbon is forced into a different phase much like ice and water. Water, methane, ammonium and an outer hydrogen-helium layer are part of the "atmosphere" of Neptune. The boundary between the liquid diamond and the slushy "gases" of the atmosphere is a gradual one, with the hydrogen-helium at the top.
Can anhydrous ammonia become liquid ammonia?
Anhydrous ammonia is typically stored as a gas under pressure, but it can be liquefied by compressing it at a temperature below its critical temperature of 132.4 °F. Liquid ammonia requires pressure to remain in its liquid state, and it is often used as a refrigerant or in industrial processes.
Why is it not possible to walk on water without any aid?
We can't walk on water because it isn't solid. It's a liquid, and liquids won't "hold things up" like solids. If we put pressure on a portion of the surface of the liquid, the molecules will just "get out of the way" of the thing applying pressure. This will allow the thing to just "go down into" the water. If you step onto the surface of the (liquid) water in a swimming pool, you'll sink.
Which planet has the heaviest atmosphere?
all planets have atmospheres. However, Mercury has extremely low atmospheric pressure, Mars has an atmosphere way below the Armstrong Limit, and Venus and the Outer worlds have way too high of an atmosphere.
