because there is is a pressure difference between the inside of the bottle and the outside. the pressure is lower in the bottle the egg gets sucked in.
when the oxygen is burned there is less matter in the bottle then at first and that results in less pressure[vacuum]
Oxygen molecules disappearing would not create a vacuum because the process would not remove all other gases and particles in the space. A vacuum is created by removing all matter from a space, not just one type of molecule. Additionally, the disappearance of oxygen would not decrease the pressure enough to create a true vacuum.
If you're referring to the common science demonstration, the answer is that the heated air in the bottle expands. When it re-cools (after the egg has been placed on the neck of the bottle) it is at a much lower pressure than the surrounding atmosphere; the weight of the air above it is then sufficient to push the egg into the bottle.
The water rose in the beaker because as the candle burned, it consumed oxygen in the air inside the beaker. This created a partial vacuum, causing the water to be pushed up into the beaker due to the air pressure outside.
When a sealed soda bottle is turned upside down in cold water, the air inside the bottle cools, causing it to contract and create a vacuum. This lower pressure inside the bottle then crushes the bottle as there is greater pressure from the surrounding water, leading to implosion.
Yes, place a flame (match, candle, etc) inside the bottle, then quickly place an egg on top. As the air in the bottle burns, the pressure will drop and the egg will be sucked into the bottle.
Because it has a vacuum.
the vacuum bottle works by having a vacuum trapped in between the lays of the bottle elimination 2 forms of heat radiation.

Another word for a vacuum bottle would be flasken.

Absolutely! A vacuum sealer removes excess air from the bottle, rather than trapping it inside as a cork does. Oxidation, or the interaction of oxygen with the wine, is what causes wine to spoil or to turn. A vacuum sealer will preserve the wine longer, therefore, because less oxygen comes into contact with it.
Understanding the components of the vacuum bottle, one can be in better position of understanding the leakage. Microprocessor monitors leakage in the Vacuum bottle.
The air is removed from the space between the two walls of a glass bottle to create a vacuum. This vacuum acts as an insulator, reducing heat transfer by conduction and convection, making the bottle more effective at maintaining the temperature of the contents inside.
The matches burn up the oxygen, removing it. This causes a vacuum, which pulls the egg in. Also the heat from the matches expand the air in the bottle. Once they have gone out, the air cools and contracts, causing a vacuum and pulling the egg in.

There is no oxygen present in a vacuum since a vacuum is an environment with very low pressure where gases, including oxygen, are effectively absent.
no
