Air applies pressure due to the weight of the air molecules above it pressing down. The higher up you go in the atmosphere, the less air there is above you, resulting in lower air pressure. The force of air pressure can be measured and is an important factor in weather systems and air travel.

How does density change as air pressure increases?
As air pressure increases, the density of the air also increases. This is because the air molecules are pushed closer together, resulting in a higher concentration of molecules in a given volume of space. Conversely, when air pressure decreases, the density of the air will decrease as well.
What happen if you push down on the plunger of a syringe filled with air?
If you push down on the plunger of a syringe filled with air, the air inside the syringe will be compressed and the pressure will increase. Depending on how much force you apply, the air may be expelled through the needle if the pressure exceeds what the syringe can hold.
Why does air pressure reduce at top of mountain?
Gravity - or, more precisely lack of it ! The further away from the centre of the earth you are - the less gravity affects apply. Standard air pressure at sea-level is approximately 14 PSI - but that reduces exponentially with altitude.
Does pascal's principle apply to air?
Yes, Pascal's principle can be applied to air. It states that pressure applied to a confined fluid is transmitted undiminished in all directions throughout the fluid. In the case of air, changes in pressure can affect its volume and density in accordance with Pascal's principle.
What crumbles the plastic bubble when you apply force to the plungder?
The force applied to the plunger collapses the air pocket inside the plastic bubble. As the air escapes, the pressure difference between the inside and outside of the bubble causes it to collapse or crumble.
How does the air pressure allow you to multiply force?
You can apply alot more force with the help of air pressure
A reading of 120 over 80 would apply to what pressure?
Air pressure
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.
A reading of '120 over 80' would apply too................... pressure?
Air
How a soccer ball bounces?
A soccer ball bounces as the air particles in them hit and apply pressure at the ball, when it hits a surface, the pressure from the particles apply a force on the ball. Thus, making it bounce.
When you put on the brakes by pushing down the brake pedal air pressure is applied to the brake pads?
In all cars and most trucks HYDRAULIC pressure is used to apply the brakes. In an air brake system such as is found on medium and heavy duty trucks the air is actually released to apply the brakes.
How do air brakes work?
Instead of using hydraulic brake fluid to apply the pads to the brake drums or discs, air pressure is used.
Why should an operator always apply the hand brake when using the hydraulic cobtrols?
air pressure is used
What happens when air gets in the braking system?
Air stuck in the brake lines cause the peddle to feel "spongy". Your braking distance will dramatically increase with air in the system. When you apply the brakes in a vehicle that has no air in the system, that pressure added with the pressure from the master cylinder presses the brake pads against the rotor or drum causing you to stop. When there is air in the brake system and you apply the brakes some of that pressure is used up by compressing the air in the system and the rest is trying to stop the vehicle.
How does density change as air pressure increases?
As air pressure increases, the density of the air also increases. This is because the air molecules are pushed closer together, resulting in a higher concentration of molecules in a given volume of space. Conversely, when air pressure decreases, the density of the air will decrease as well.
When was Apply Some Pressure created?
Apply Some Pressure was created in 2007.
What happen if you push down on the plunger of a syringe filled with air?
If you push down on the plunger of a syringe filled with air, the air inside the syringe will be compressed and the pressure will increase. Depending on how much force you apply, the air may be expelled through the needle if the pressure exceeds what the syringe can hold.
