How does some devices that uses air pressure work?

Answer 1

Air has weight. You want proof? weigh a balloon, then blow it up and weigh it. Difference? Yes Anyway all things have gravity. The larger the thing, the more gravity it has. The sun for instance has planets revolving around it because of its great size. The Earth though, only has a moon. The weight of the air presses down on everything, even us. When air pressure is greater on the inside of something, it will bulge out. When it is greater on the outside it will push in. A classic example is popping your ears. When you go up a mountain or something the outside air pressure weakens (all the heavy air sinks). This means the air pressure in you is greater than the air outside. This is why you will get a headache. Popping your ears how ever, blows the air out of your ears so that the difference is less. When you go down the mountain the opposite happens.

Answer 2

Air pressure is the amount of space between each particle of air, measured in denominations of pascals (Pa), pounds per square inch (psi), millimeters or inches of Mercury (mmHg / inHg).

In weather, a breeze of wind is created by two regions of differing air pressures. The high-pressure area will always flow to the lower pressure point, very much like water pressure in a sense.

Answer 3

Devices that use air pressure typically work by trapping a certain volume of air within a chamber or container. When the air pressure changes inside the chamber, it creates a force that can be harnessed to perform a specific task, such as pushing a piston or turning a turbine. By controlling the flow of air in and out of the system, these devices can generate mechanical or electrical energy for various applications.
