The atmosphere (the air above you) naturally applies air pressure as a result of Earth's gravity. In other words, because it is made of matter it has weight.

How does density change as air pressure increases?
If you have air in a tight cylinder piston system, when you apply pressure you will see the volume of the air reduced. The amount of mass of air is the same, but now it occupies less volume, the molecules are closer together, its density has increased.
What crumbles the plastic bubble when you apply force to the plungder?
a plunger crumples when pressure is applied because the presume pushes out the air creating a vacuum and the air pressure on the out side is more than the pressure on the inside creating a suction effect and causing it to crumple
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.
Wherever the balloon is what can you say about the pressure of the air inside and outside the balloon?
Usually, the air pressure inside a balloon is very high because the plastic outer shell of a balloon wants to contract and press the air into a small space. High in the atmosphere, air pressure is much lower than on the ground. When the air pressure outside a balloon is bigger than the air pressure inside, the balloon switches from wanting to push in on the air to the air pushing on the balloon. as this happens to some parts of a balloon and not others, it is uneven and the balloon pops.Answer:There are two distinct cases:For child's rubber balloon the air inside is at higher pressure because it is being squeezed by the rubber that wants to return to its original size. Just like you have to apply pressure to a rubber band to keep it stretched.In the case of hot air balloons the pressure on the inside of the balloon is the same as the atmospheric pressure. The balloon in this case is like an upside down bucket of air that would like to rise. It fills the container but shares the pressure of its surroundings.
What effect does cold air have on air pressure?
Cold air increases air pressure
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 does density change as air pressure increases?
If you have air in a tight cylinder piston system, when you apply pressure you will see the volume of the air reduced. The amount of mass of air is the same, but now it occupies less volume, the molecules are closer together, its density has increased.
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.

What is the weather term of how heavy the air is?
Air Pressure
