Passiert etwas wenn man ein verschlossenes Gläsernes Gefäß mit in die Luftfracht nimmt? Passiert da irgendwas wegen dem Luftdruck? Kann es zerbrechen?

In my knowledge, the cargo compartments should be pressurized for both passenger and normal cargo aircraft. Accordingly, air pressure prevails in the flight (as long as everything goes well) as on a 2600 m high mountain.

Now consider if you were afraid of your glass vessel if you were going to a corresponding mountain by car.

If it was closed airtight on the ground, then a force would have to act on the vessel at the top in the air when there is another ambient pressure.

If the force is too strong it can break.

Makes sense. In order to avoid this, it may be possible to pack the glass vessel into a more stable, airtight vessel, then it is protected from the pressure difference of the ambient air. Or you transport the vessel unclosed.

Nonsense!

It’s crazy! If there’s something wrong with my answer, say something!

When the pressure acts on the closure, it requires less pressure to open it far enough that air can escape as it needs to allow water to escape.

In a beverage bottle is usually also more water than air, so it can exert more pressure overall (and can be compressed less strongly by the pressure itself than air).

This knowledge should be clear to every child in preschool age, but it remains questionable, which is why this should have an effect on the pressure inside the glass. When the pressure inside the glass presses on the glass wall with 500 hectopascal, it can be no matter whether the pressure is caused by a liquid or by a gas.

Not a liter but a kilogram, it’s about density. It’s higher in water.

Luftkutscher

Why should one liter of water need more space than one liter of air? By the way, the glass vessel does not care whether it is the pressure of gases or the pressure of liquids, provided it is below the burst pressure.

The escape of air can, however, occur earlier than the escape of water, since air takes less space. In addition, air has a lower density, which makes the formation of high pressures more difficult due to temperature differences.

This is completely irrelevant whether the pressure through the ice or through air or through other gases presses on the interior of the bottle and on the closure. Only the height of the pressure is decisive.

if you put a beer bottle or water bottle into the icebox, for example.

That’s not an air pressure when I’m not mistaken.

Functional closures keep the resulting pressure loose because they are designed for this purpose. Only by improper treatment can the pressure become too high if, for example, a beer bottle or water bottle are placed in the ice compartment.

You can shake a bottle or a champagne bottle yourself without placing it through the resulting pressure

What is probably due to the fact that the carbonic acid does not dissolve out of the water if the ambient pressure is already too high (by previously expelled carbonic acid).

Only faulty closures could yield.

With too high pressure also functional closures. That’s what I meant with air permeable.

No, they can’t. It is possible to shake a sparkling bottle or a sparkling bottle without bursting through the resulting pressure, because the pressures generated thereby move in the range of a few hundred hectopascals. This holds out any cheap glass vessel. They also do not become air-permeable. Only faulty closures could yield.

Simple glass vessels can then be brushed or air-permeable at too high pressure.

Yes, for containers that have to withstand particularly high pressures, such as, for example, pressure boilers, steel bottles for compressed air and technical gases etc… there are DIN regulations and these must also be tested in a certain period of time TÜV. For simple glass vessels, this does not apply

NoBlizzard

It also depends on how much pressure they have to withstand. I’m sure there’s some standard for or something.

All vessels to be transported in the liquids must be airtight, otherwise they could run out or germinate.

NoBlizzard

Jogurt glasses are airtight. They always open at first.

Luftkutscher

Yes, because otherwise it would possibly run out during transport or gas out at Sprudel. Have you never opened a bubble bottle and noticed how it squeaks?

NoBlizzard

A water bottle is not really dense either.

Luftkutscher

Each water bottle is airtight and if any glass vessel should not be airtight, then the air pressure does not matter at all, because then the pressure can compensate

NoBlizzard

Normal glass vessels are also not airtight. This is something special.

So filigran is not a glass vessel, because otherwise they would break when driving over mountain passes or even filling in any liquid.

NoBlizzard

I didn’t say the power was strong. And even if it is not strong, it also depends on the stability of the glass vessel.

Luftkutscher

Your answer is nonsense, because the pressure difference is only a few hundred hectopascal, and that keeps every glass vessel loose.

Luftkutscher

No, there’s nothing happening. The pressure difference is at best a few hundred hectopascals and this keeps every glass vessel loose.
