A pressure bag for an arterial line setup is typically inflated to 300 mm Hg to ensure adequate pressure for accurate blood pressure monitoring.
The air pressure is the same, inside or outside the paper bag.
increases. This increase in air pressure can cause the bag to expand outward, in an attempt to reach equilibrium with the surrounding pressure.
The pressure required to make a bag explode depends on a variety of factors, including the material the bag is made of and its thickness. However, a common range is 2 to 4 times the normal atmospheric pressure.
You can increase the air pressure inside the bag by reducing the volume of the bag or adding more air molecules to it. This can be done by squeezing the bag to decrease its volume or blowing air into the bag to increase the number of air molecules present inside.

At higher altitudes, the air pressure surrounding the bag of chips decreases while the air pressure inside the bag remains the same. This pressure difference causes the bag to expand and appear inflated like a balloon.
As the bag of balloon rises, the pressure inside the bag of balloon decreases. Air pressure generally decreases as the altitude increases.
Funny, I hadn't noticed that before. But if they appear inflated, it is because they are bagged and sealed on the ground, probably pretty close to sea level. However, the cabins of airliners are pressurized to 8000 feet. So the air pressure outside the bag, being lower than the pressure inside the bag, causes the air inside to expand and inflate the bag.
If it remained inflated then you would have difficulty getting out.
The bag's internal pressure, when fully inflated is about 10 to 30 kPa, which is comparatively low but sufficient to safeguard the driver if dashed against it. The drivers thrust on the air-bag pushes gas to escape through two large outlet holes in the rear of the bag to further cushion the impact.
The bag of a bagpipe is inflated by blowing through a blowpipe.
Bags of chips (crisps) can expand in an airplane. A bag of chips on the ground doesn't appear to be inflated because the outside air pressure is high. As the elevation increases (like in an airplane) the outside air pressure decreases, which means that there is also less pressure in the bag. As the pressure decreases in the bag, the gas inside wants to take up more room and it expands (similar to what happens when the pressure is released from a can of soda). However, the cabins of most airplanes are pressurized, so you would not be able to see any expansion.
It decreases the impulse of force.
The air pressure is the same, inside or outside the paper bag.
When a sealed bag is compressed and more space is available in the bag, the air pressure inside the bag decreases. This is because the air molecules are now occupying a larger volume, leading to a lower pressure.
increases. This increase in air pressure can cause the bag to expand outward, in an attempt to reach equilibrium with the surrounding pressure.
A deflated ziploc bag should hit first due to less air resistance. If it was not for air resistance they would hit at the same time
