oxygen flammable?

Question

see i was always told that oxygen was flammable. and if you were in a 100% oxygen environment and lit a match it would all go kaboom. but now i hear that its not flammable. so i guess my question is:

if i were to somehow fill a vacuum sealed room with all oxygen, and lit a match what would happen.

thanks. and umbrella, thats just because its compressed air, if it heats up it gets more pressurized, and the tank cant hold the pressure and it breaks.

Answer 1

You've got to understand what fire is.

Fire is the energy and material released when a substance quickly reacts with oxygen. Oxygen is everywhere, so you might wonder why things don't catch fire randomly.

In order for something to burn there are two conditions. One, it must be touching oxygen, and two, it must be at the proper temperature.

A match burns because the striking motion gives the heat, and the chemicals on the match react with oxygen.

Oxygen CANNOT react with itself. That is, O2 cannot react with itself. We breath O2, so I assume that is what you mean. Oxygen is almost never just by itself.

In conclusion, OXYGEN CANNOT BURN LIKE THAT. If there were, say, another gas like methane, then methane could react with oxygen and create a fire, but oxygen does not react with itself. The match will burn until the chemicals on it run out.

Hope that helped.

Answer 2

Oxygen Tank Flammable

Answer 3

I think oxygen is not flamable. the match will burn just like it would if you struck it in a normal air filled environment. the match in the oxygen might only last half as long as it would in air because it would burn faster in pure oxygen.

Oxygen does not burn. Oxygen supports burning. there must be something esle also with the oxygen in order for burning to be possible. You need a fuel and oxygen for burning to happen. if all you have inside a sealed container is oxygen and a spark plug and you spark the sparkplug there will be no explosion. but if you put petroleum vapors AND oxygen down into an engine cylinder and then set off the spark there will be an explosion (thats how gas engines work).

there must be something else beside oxygen in order to burn.
when you first strike a match the fire is brighter and thers a sound. the chemicals in the match head are burning...phosphorus and sulfur i think. but after second or two you notice there is no sound but the match is still burning thats when its burning the paper stem of the match. oxygen supports the burning sulfur and then the burnning paper.

when an oxygen tank gets hot it will explode because the gas inside will become more pressurized and the bottle will burst open catastrophically and gas will excape violently and throw the bottle around as it excape. but any gas will do the same thing. a bottle full water will burst open and explode if you get it too hot but there will be no fire, no burning.

The answer is resoundingly NO. Oxygen is NOT a fuel. Flames, fire and all related chemical reactions are a result of a FUEL being OXIDIZED, or being combined with oxygen. The application of oxygen to a burning fuel will cause the fire to burn much more vigorously, as well as hotter. Oxygen, by itself, WILL NOT BURN. If it did, our atmosphere (which is 20.9% oxygen) would have burned up a long time ago. Oxygen is mixed with a number of different fuel sources to get a faster, hotter burn. Acetylene, used in metal cutting torches, is mixed with oxygen to get a super hot flame that will quickly cut through metal. NASA uses oxygen to burn hydrogen fuel, not only to get a fast burn required in a rocket engine, but also because surrounding oxygen in the atmosphere becomes much more scarce as you leave the atmosphere for space.

Answer 5

by it's no but you need 3 items for fire or explosion
1 fuel any thing that will burn
2 air. oxygen is only 21.x %
3 spark

pure oxygen with the other above could cause the small flame burn so fast it would be an explosion

Answer 6

Oxygen cannot burn by itself. It needs another element or compound to make a chemical reaction possible. There are, however, a very great number of things which will burn rapidly or explosively in a pure oxygen environment. Cloth or even hair saturated with oxygen will produce a flash fire if ignited.

Answer 7

For starters you cant fill a vacuum because its already empty but you can fill a leak proof room. Anywho the match will only burn as much oxygen as it needs to complete the reaction. There will be a larger flash of fire then you are used to. much larger actually but the entire place will not burst into flames

Answer 8

While oxygen IS flammable - there must be a particular delicate balance of fuel versus fire for it to properly burn. (Ever watch that Mythbusters episode where they couldn't get the mixture right of gasoline vapor in a room to ignite it with an open flame??)

A 100% oxygen filled container plus an open flame could definately result in a big ol' "Ka-boom" ...

Answer 9

it IS flammable. it will go kaboom.
my cousin had oxygen tanks because of a medical condition and his doc told him not to keep it in the heat cause it would blow up since it's flammable.
