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.

∙ 9y agoAir 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.

What uses air pressure to work?
air
What are laser measuring devices used for?
Laser measuring devices are generally used in construction-related work. Uses of laser measuring devices in such a situation include measuring distance, and seeing if an object is level.
How do lighter than air devices work?
bob the buildder
How do adhesives work?
Some adhesives soak into the material then dry out. Others are pressure sensitive, and others have a chemical reaction.
Can you use a 12V power adapter on a device that requires a 6v adapter?
No, the voltage is too high by 25%. maybe. in many cases it will not work. However, some devices convert the input voltage to a lower internal voltage like 5V and then the higher voltage adapter may work. However, it could lead to other problems like overheating, so it is not a good idea. Many devices specify a range of input voltage
What uses air pressure to work?
air
Do Indian electrical devices work in US?
No India uses 240V at 50Hz the U.S. uses 110V at 60Hz.
How do you use this energy?
it energy makes our light and other devices that uses electric work
What is a technology that uses fluids under pressure to do work?
hydraulics
What is the difference between wind mill and wind turbine?
Wind mills are mechanical devices that uses that power to do work. Wind turbines are electromechanical devices to work for us by making electricty.
What is the difference between hydraulic and hydrostatic?
hydraulics uses the principle of hydrostatic pressure to work
What are laser measuring devices used for?
Laser measuring devices are generally used in construction-related work. Uses of laser measuring devices in such a situation include measuring distance, and seeing if an object is level.
How is time measurable by physical devices if it is not a physical quantity?
Well, some physical devices don't work at all.
What are some electromagnetic devices?
electromagnetic devices are devices that work on electricity but are magnetic
What are two uses for?
You have two uses so if one of your uses do not work you can always use the other use. If your other use does not work then make some more uses if they do not work make more uses and so on!
Where can you find out which mobile devices are compatible with Google maps for mobile devices?
Google maps work on a number of moblie devices including Android powered devices, most J2ME phones, Palm devices with Palm webOS and Palm OS5+, color Blackberry devices, Windows Mobile devices 5.0 +, and 3G Symbian devices. Be aware that some features may not work on all devices, and limitations of mobile service providers may affect some applications.
