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)
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 do you dispose of liquid nitrogen?
The safest way is to put it in an open space away from people and let it harmlessly boil off into the atmosphere which is 79% nitrogen anyway.
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.
What is it called when something changes from a liquid to a gas?
If it happens below the boiling point it is called evaporation. At the boiling point it is boiling.
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 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.
How is pressure affected by the depth below the surface of a fluid?
Think like this if you but sand in a bucket with a balloon in the bottom will the balloon be crushed? its the same way with water or any liquid the deeper you go the more of the liquid is pushing down on you which makes pressure rise.
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.

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.
What is ideas about vapour pressure to explain how impurities increase the boiling point of water?
The boiling point is the point at which the vapor pressure of the liquid reaches atmospheric pressure. So, if you add impurities (solutes) to the pure liquid, the theory is that those molecules get in the way of the solvent molecules, and at the surface that results in a LOWER vapor pressure of the liquid. This then results in an INCREASE in the boiling point, because remember that boiling point is when vapor pressure = atmospheric 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
Which planet has a thin atmosphere besides Mercury?
Mars has the next thinnest atmosphere, a thin carbon dioxide atmosphere. Although thin, it's much more substantial than anything mercury has got in the way of surface pressure.
Can anhydrous ammonia become liquid ammonia?
Anhydrous ammonia is usually stored as a liquid by keeping it under pressure. It is more efficient to store it that way than as a gas.
