What happens to a half-full plastic water bottle in an airplane when flying from low into high altitude?

Question

is it going to be crushed (due to the pressure) or is it going to expand (like air does within air impermeability packages)?
What is the reasoning behind it?

Answer 1

I hike and climb mountains a lot with my water bottle. On the way up, it will expand, maybe even pop open and leak depending on your stopper.

The reasoning is air, like water in a lake, stacks up on top itself and creates pressure depending on how much air or water is above it. Air on earth stacks up to about 12 miles high at sea level. A column of air 12 miles tall weighs 15 pounds per square inch. It is not weightless as it feels to us. Of course, air is compressible. So the air at the bottom of the 12 mile tall column is squished and takes up less space than air six miles up in an airplane that is only under about 6 pounds per square inch of pressure from a 6 mile tall column of air above it. As the air pressure in the bottle is at 15 psi and the air pressure outside is at 6 psi or so, the air inside the bottle pushes out an expands the bottle or pushes the top open. Of course this assumes an open cockpit airplane. In pressurized passenger planes, they only allow the cabin pressure to drop to the equivalent of flying at about one mile up altitude. That's why if you break a window higher up, all the air rushes out the broken window until the air pressure is equalized inside and outside the plane.

Answer 2

it will expand and may be explode (if there is a hole on the plane or an open window or something like that but if there is nothing like that nothing would happen to the bottel)
the reason for that is the bottel is half filled with water that means it is half filled with air . and as u have closed the bottel on the ground the air will have a pressure of lets say P1 at this moment the out side air pressure is equal to the inside on . so no force affect the bottel
but when the airplane goes up the outsite pressure is decreasingwhile the inside pressure is constant so there will be a difference in pressure which will cause a force in the direction of the lower pressure(outside)
as the plane fly higher an higher the pressure difference become greater and so do the force

Answer 3

There are diverse altitudes for various purposes. Airliners fly so intense on the grounds that's budget friendly. different planes like protection rigidity have their very own air area to play in even in the event that they'd fly everywhere with a flight plan. same with prevalent aviation. there is likewise a fashion of assigning altitudes including those flying North fly and a wierd top and those going South fly at an excellent altitude (merely an occasion).

Answer 4

It will expand slightly because the air pressure is maintained at 7,000 ft.
