The vacuum of space. would it ill in area?

The vacuum of space. would it fill in area?





sorry for the misspellingThe vacuum of space. would it ill in area?
Vacuum means there's nothing there. So if you took a zip lock bag into space and sealed it, it would be flat, the same as if you never opened it - there is no gas in space for the bag to trap (well, there is a tiny bit, but not really enough to make any difference). So you wouldn't be able to squeeze it or pop it in the first place.





It would be a little different if it wasn't a zip lock bag. Suppose instead it was a bag that naturally wasn't flat - possibly globe shaped or cylinder shaped more or less. If you sealed it out in the vacuum, it would retain its shape while in the vacuum. But as soon as you brought it into an area with air pressure, it would be squashed flat, even though it was still sealed, because there is nothing inside the bag to resist the air pressure outside it.





You can even demonstrate this for yourself, somewhat, if you are ever on an airplane. Even though you are never in a vacuum, when the plane is at its maximum altitude, the air pressure inside it is less than normal. So if you filled a bag with air and sealed it in the middle of the flight, when you landed you would see that the bag had gotten smaller, even though it's still sealed.The vacuum of space. would it ill in area?
Open it? The air would just rush out.





Squeeze it really hard?


It would pop open like normal, because the pop is created by pressure.





However, It would probably pop open by itself, because there is pressure from inside the bag, but not from the outside since it's a vacuum.





When it does pop, you would not hear it, as their is no air to transmit the sound waves to your ear.
