how does air pressure apply to the real world?

Answer 1

The amount of air pressure in the tyres in your bike or auto is fairly important. It's a rather elementary part of balloons, and gas pressure is very important in things such as aerosol cans. It's also very important in weather -- you can tell a lot by changes in air pressure, from what you may expect the temperature to be, whether you can expect rain or a clear day, and (if there's a sudden drop in air pressure) if there's a storm coming.

Answer 2

Stress- people who experience too much pressure!
- how about things like pop- where carbon dioxide is naturally formed by yeast or by artificial means while enclosed in a bottle where the outside pressure of air pushes against the inside contents forcing the carbon dioxide to dissolve in the particular solution. Without air pressure and other forms of pressure (like under the ocean), many life forms would not be able to keep their shapes because there would be no forces acting on their surfaces to push against the forces pushing outwards from within the particular life forms (like humans).

Answer 3

Air pressure allows you to breathe, has impacts on the boiling and freezing points of substances, and creates wind and weather patterns. All of these are fairly important to the real world.

Answer 4

Air pressure (barometric pressure) is pretty large in determining our weather. The decrease or increase in air pressure as you go up or down a long hill - or take-off or land in an airplane - is what causes your ears to "pop". Manufacturers of barometers love it as it keeps them in business!

Answer 5

filling your car tires with air at the gas station

Answer 6

It keeps the oceans, lakes and rivers from boiling, and bags of salty snacks from exploding.
