What is Vacuum oxygen decarburization process?
The VOD (Vacuum Oxygen Decarburisation) process is used for production of high chromium steels with lowest carbon contents. it is a type of furnace in which the molten meatal is placed under a vacuum chamber....
How do you remove oxygen from a test tube?
To remove oxygen from a test tube, one method is to displace it with an inert gas, such as nitrogen or argon. By flushing the test tube with the inert gas, the oxygen is pushed out. Another method is to create a vacuum inside the test tube to remove the oxygen. This can be done using a vacuum pump or a syringe to pull the air out of the tube.
Does carbon burn in a vacuum?
In normal usage, 'burning' means oxygen combustion, so without a source of oxygen carbon cannot burn. Rockets get around this problem by carrying supplies of oxygen with them (although rockets usually burn hydrogen rather than carbon compounds). Further, given sufficient temperatures, carbon compounds may react chemically with other available substances, which may be considered a kind of burning
Do tornadoes have no oxygen?
There is air and thus oxygen inside of them. Contrary to popular belief, although pressure is low inside a tornado it is not a complete vacuum.
Is Earth's atmosphere a vacuum?
Look at the diagram below: This is the molecular arrangement in gas, liquid and solid. We can say that the first jar represents the atmosphere of the Earth. If the air molecules in our atmosphere are arranged like this, there should be lots gap between them. What is there in this gap? If there is nothing in this gap, then there should be vacuum. So there should be vacuum in air. That is probably one of the funniest and best answers I have seen. A vacuum is a total lack of substance, of any kind. Since the atmosphere has substance then, by definition, it is not a vacuum
Which animal can respire in vacuum?
none, because you need oxygen to respire and a vacuum is the absence of matter and oxygen is matter
What happens to fire in a vacuum?
It will go out. Fire needs oxygen, and a vacuum has none.
What is the difference between an oxygen vacuum and a regular vacuum?
The oxygen cannister has a higher filtration which is more expensive but great for your home,especially for allergy suffers etc.
Another word for zero oxygen environment?
Vacuum
Would fire burn in a vacuum?
A substance would only burn in a vacuum if it contained an oxidizer. There has to be an oxidizer for there to be fire. That doesn't mean that it requires oxygen, just a substance that facilitates the removal of electrons.
What are the elements of a vacuum tube?
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).

What will happen to lighted candle in a vacuum?
In a vacuum, a lighted candle will eventually extinguish due to lack of oxygen for the combustion process to continue. The flame will consume the available oxygen in the immediate vicinity and go out once there is no more oxygen to sustain it.
Why is unlikely that the disappearing oxygen molecules could have produced a 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.
Can you catch oxygen?
with a vacuum or some special technology, but not really with your hands
Why cant you light a match in space?
No. Because there is no oxygen as there is only vacuum.
Why does oxygen content decrease in water left stagnant over several days?
As the water is poured into the glass, some oxygen dissolves in it. If the water doesn't move, the oxygen slowly diffuses out of it. If you were to pour in the water in a vacuum and then removed the vacuum and left the water stagnant, there would be no oxygen content decrease.
