Why does a syringe plunger go back in if you pull it out?
When the plunger is pulled, the volume inside increases. This reduces the pressure inside, and the air pressure outside forces liquid in, in an effort to make the pressure inside and outside the syringe equal again.
How can your bodies keep from being crushed by air pressure?
Your bodies pressure inside your body can change itself tone equal to outside pressure
In an open system the vapor pressure is equal to the outside air pressure?
Yes it is equal
Why aren't organism on the seafloor crushed by water pressure?
Pressure on the inside is the same as the pressure on the outside. No different from why doesn't the air pressure of 15 psi not squeeze us flat.
Would there be more air pressure in a balloon at sea level or high in the sky?
provided the balloon has not reached its elastic limit (it has burst!), the air pressure inside and outside will essentially be equal. [The pressure inside will be slightly less, which is where the lift comes from.] But even at altitude, the pressure will be approximately equal in and out, for at altitude, the balloon will have swelled, thus reducing the internal pressure. It will eventually reach an altitude at which the internal pressure and the external pressure will be equal, and the balloon will have reached maximum expansion. Filled at sea level, a balloon will seem empty and floppy, and very tall and thin. At altitude the balloon will fill out as the external pressure reduces.
The air pressure inside the can compare to the air pressure outside the can equal lower or higher?
There is no difference of the average local air pressure inside or outside of the headphone.

Why does a difference in air pressure crush things?
A can or container can stay rigid due to equal pressure from the inside and the outside. When the atmospheric pressure from the outside increases mote than the pressure pushing out from the inside, the material gets crushed.
If the pressure inside a car tire is equal to atmospheric pressure the tire is flat why?
If inside and outside same pressure that means there is no pressure. The added pressure is what blows the tire up like a balloon and holds the weight of the car up.
Is the pressure inside the balloon equal to the atmospheric pressure?
Think about this: if the pressure WERE equal, what would happen in the instant when you open the neck of the balloon and whatever pressure is on the inside meets the pressure that is on the outside (atmospheric pressure)? In your experience, what DOES happen?

In an open system is the vapor pressuse equal to the outside air pressure?
In an open system the vapor pressure is equal to the outside air pressure.
In an open system the vapor pressure is equal to the outside air pressure?
Yes it is equal
Air pressure at sea level is 14.7 pounds per square inch why aren't we crushed by this force?
Because the pressure inside our bodies and outside our bodies are equal.
Why does an empty sealed bottle collapse with altitude?
Actually, an empty sealed bottle should expand slightly as altitude increases. At the altitude where the bottle is sealed, the air pressure outside the bottle is equal to the air pressure inside the bottle. When the bottle is transported to a higher altitude, the air pressure inside the bottle is greater than the air pressure outside the bottle (In other words: There are more air molecules per unit volume inside the bottle than outside). The increased air pressure inside the bottle relative to the outside pressure causes the bottle to expand slightly. An empty bottle would not collapse as altitude increases.
Why when the air is sucked out a bottle it collapses?
When an empty plastic bottle is left open to the atmosphere the air pressure outside and inside the bottle are in equilibrium (does not always mean they are equal, but in this case they are equal). This means that whatever force exerted by the atmosphere on the outside of the bottle is balanced by a force from the inside of the bottle. When one sucks the air out of the bottle one removes the source of pressure and forces within the bottle. The pressure differential between air outside and inside bottle is enough to cause the bottle to collapse.Note that this will not happen so easily with glass bottles because even when one tries to suck all the air out of them, they also experience a tendency to collapse, but their structure is strong enough to withstand the pressure differences.
