The automotive 'airbag' is actually more like a 'parachute' as it has holes on the forward facing surface (towards the windshield) for the gases to escape. The 'airbags' are inflated by a solid chemical charge (like gunpowder) that is ignited by an electric spark. When i worked in a QA Lab testing these charges the pressure, at that time, was measured in kpa (kilopascols). If i remember correctly, the airbag deploys at a speed between 170-200 miles per hour. I recall scientist stating that a wind speed of approximately 300mph will begin to cause severe damage to the human body.

What is the air pressure inside a papper bag?
The air pressure is the same, inside or outside the paper bag.
Why does a chip bag increase in size when driving up a mountain?
The chip bag is sealed, and no air can get inside it. The air pressure decreases as you get higher, so the air inside the bag expands to equalize the pressure on the outside of the bag.
Why doesn't a closed paper bag collapse under the weight of earth's atmosphere?
The bag does not collapse because the air pressure acting on the inside of the bag is equal to the air pressure outside the bag (There are the same number of air molecules per unit volume inside the bag as outside). However if you had filled the bag with air at high altitude where the air pressure is lower, then sealed it and brought the bag down to sea level you would find that the higher external air pressure (there are fewer air molecules per unit volume inside the bag than outside) would begin to compress the bag down to a smaller volume. This in turn would compress the air inside the bag leading to an increase in its pressure. This decrease in volume will continue until the air inside the bag is compressed to the point where its pressure is equal to that of the external air pressure. For further information on this topic it may be worth searching for the term "Combined Gas Law" which will explain the relation between pressure, temperature and volume.
Does the pressure inside the bag of balloon increases or decreases?
As the bag of balloon rises, the pressure inside the bag of balloon decreases. Air pressure generally decreases as the altitude increases.
How can you increase the air pressure inside a bag containing a group of air molicules?
you break the bag into four pieces
When a sealed bag is compressed less space is available in the bag and the air pressure?
increases
Parachute is to Airplane as Air Bag is to?
car...
What does it mean if car says service air bag?
The air bag system is not operating correctly. If the car is involved in an accident, the bag may not deploy, causing greater possibility of injury.
Do air bags contain air?
Its an air bag. Yes, it has air in it. When a car crash happens, the bag fills up with air very quickly.
Why doesn't a closed air bag collapse under the weight of earths atmosphere?
The pressure inside the bag is the same as the pressure outside.
Whes a sealed bag is compressed more space is avaiable in the bag but the air pressure?
it will rise
Why is a bag puffed up when you are 3000 meters high?
It was packaged at a lower elevation where the air pressure is higher. As you move to a higher elevation the external air pressure decreases, but the air pressure in the bag stays the same. So the bag "blows up" like a balloon because the pressure inside it much greater than the pressure outside. Same thing happens in your ears.
