Compressed Chamber: Perfect Vacuum, Pull Apart?

In summary: This was helpful!In summary, when there is a closed chamber of air, there will be an inside pressure and an outside pressure. The outside pressure will apply force to hold the chamber together. The inside pressure will apply force to take the chamber apart. If the chamber is pulled apart, the inside pressure can be helped by pulling on the chamberhalves.

Just thinking here. What would happen if you had two pieces of something that connect perfectly and form a chamber of air inside. Then you took all the air out to make a perfect vacuum. Now if you were to pull the sides would it break apart. I don't understand how there would be a perfect vacuum inside that would hold the unit from seperating. If there is no air then it should be impossible to pull it apart right?

Not impossible. What holds them together is the air pressure outside of them pushing them together.

I still don't understand how the inside of it could possibly expand. There is nothing to expand? Maybe I don't fully understand what a vacuum really is.

Expansion doesn't matter here.

When there is a closed chamber then there will be an inside pressure and an outside pressure.

The outside pressure will apply force to hold the chamber together.
The inside pressure will apply force to take the chamber apart.

Wether the chamber will come apart or stay together becomes a contest between the outside and inside pressure.

The inside pressure can be helped by pulling on the chamberhalves.

Once Fpull + Finside > Foutside the chamber will break.

Since a vacuum is just empty space, it doesn't matter what size it is.

Again, what most people get wrong about a vacuum is that they think it somehow pulls on things. Since it is just empty space, how can it be pulling on anything?

Thanks you guys.
 

1. What is a compressed chamber?

A compressed chamber is a sealed container or vessel that is designed to hold gases or liquids at a higher pressure than the surrounding environment. This is achieved through the use of a pump or other means to increase the pressure within the chamber.

2. What is a perfect vacuum?

A perfect vacuum is an ideal state in which there is no matter or gas present in a given space. This can only be achieved in theory, as it is impossible to completely remove all particles from a space. However, a high level of vacuum can be achieved in practice.

3. How do you create a perfect vacuum?

A perfect vacuum cannot be created, but a high level of vacuum can be achieved by using a vacuum pump to remove air and other particles from a chamber. This can create a lower pressure environment, but it will never be completely free of particles.

4. What is the purpose of a compressed chamber?

A compressed chamber is often used in scientific research and industrial processes to create a controlled environment with a specific pressure and composition of gases or liquids. It can also be used to test the effects of extreme pressure on materials or to conduct experiments in a low-pressure environment.

5. What are the dangers of working with compressed chambers?

Working with compressed chambers can be dangerous if proper safety measures are not taken. The high pressures within the chamber can cause explosions or implosions if not handled correctly. In addition, certain gases or liquids used in the chamber may be hazardous to human health. It is important to follow safety protocols and use appropriate protective equipment when working with compressed chambers.
