If you are refering to an air bag in an automobile, then those bags are filled, very quickly, from a pyrotechnic device called a gas generator mounted at the base of the bag.
Small sensors mounted in the car sense when you hit something hard and they ignite the pyrotechnic charge, which burns rapidly, releasing a lot of gas into a bag on the steering wheel, dashboard on headliner of a car. The bag fills and then deflates very very fast. FAST is the key thing here.
because of air exerting pressure from afar it is possible to fill the bag with air in first breath if blown from near it may take around 70 breaths to fill the bag.
Not on most cars. The air bag is a self contained unit that uses a chemical compound to fill the bag with harmless nitrogen gas.
You start to fill dizzy.
Yes and no, depends if its an electronically controlled with sensor air bag, 1990's thru 2002 the air ride suspension is electronically controlled, if you have this you cant fill them manually, the only way you can fill a suspension manually is if you have air filled shock absorbers, there is a little black nipple on the side you add air from an air pump so your suitable air ride height, do not attempt to add air to an ECAB on lincolns.
replace the air bag before you burn up the pump
If you cannot find where to fill the air bags with air, follow the air line from each bag and see if you can find an air line connector,My thought is that it's somewhere near the airbag.
There should be an air valve in the engine compartment driver side on the compressor. with a air hose (like the gas station have) you could fill it up, but you need the selonoid on the air suspension bag to open up to fill front of the car or back. In the trunk of the car next to the air supension on or off switch, you will find a lose wire with a plastic head, place that lose wire on the screw that's close by. (meaning ground) make sure air supension switch is on,and turn key on while getting ready to filled bag with air hose. open and close door to fill front air bag and repeat for back airbag. when done remove the ground wire near the on and off switch. it is actually a test to fill bag when need too. after filling bag tuen air suspension off or you will lose the air.
Fill the bag with peanuta
For an experiment on how air takes up space, you will need a container (such as a balloon or a bottle), water, a bowl, a ruler, and a source of heat (like a candle or a lighter). Fill the container with water, heat the air inside the container, observe the water level change as the air expands, and measure the new water level with a ruler to demonstrate that air takes up space.
You might not find this answer the best, but to remove the air simply open the bag a bit and suck all the air out and as you are sucking the air out close it. I have found that if you fill a kitchen sink with water place the bag with the open side just above the waterline and zipping it closed while under water works great.
Just the air bag
The mass of the bag with air will be the sum of the mass of the bag itself and the mass of the air inside it. The mass of the air can be estimated by knowing the dimensions of the bag and the density of air at the given conditions.
