it would go out, because for the fire to stay lit one necessity is oxygen.
CO2 is th gas used, if you starve a fire of oxygen then it wont have anything to burn
oxygen
Oxygen is the gas needed for burning in the fire triangle. Without oxygen, combustion cannot occur.
Let's change this: what happens when gas hits fire? One molecule isn't enough to do anything. A fire needs three things to burn: fuel, oxygen and heat. If you hit a fire with a gas, one of three things can happen to the fire, depending on what gas you used. If you used a fuel gas, the flame will increase in size if there is enough additional ambient oxygen to react with the added fuel. (If your fire is in free air, there will be.) What happens to the molecule depends on what specific fuel gas it is. If you're burning hydrogen, it will combine with oxygen and become water. If you're burning a hydrocarbon, it will split up; the carbon will become CO2 and the hydrogen will become water. If you use inorganic fuels - ammonia and hydrogen peroxide are both flammable - you will get whatever reaction product that molecule will give you. If you used oxygen, the flame will also increase in size. Oxygen itself is not flammable, but fires require oxygen to burn so adding oxygen will make the fire burn better. If you used a nonflammable gas like carbon dioxide, it can do several things. It could shield the flame from oxygen or cool it, either of which will put the fire out.
Fire needs Oxygen gas to burn. The water pushes the Oxygen gas away from the fire, preventing it from burning.
Any gas will put out a fire except for oxygen or an oxidant.
Well a fire normally needs Gas Air and Oxygen so it burns when you turn the gas on the fire will automatically shows up because you are completing the triangle to make fire which is GAS+AIR+OXYGEN=fire
Oxygen is the gas needed to make fire. It supports the combustion process by reacting with the fuel to produce heat and light.
If a split that is on fire is placed into a container containing hydrogen gas and oxygen gas, the split will react with the hydrogen and oxygen gases causing a combustion reaction. This reaction will produce water vapor and release a large amount of heat and light. It can result in an explosion due to the rapid combustion of hydrogen and oxygen.
Oxygen
Because fire needs oxygen to burn and there is no oxygen inside the cylinder. It is almost impossible for the gas inside to catch fire.
An asphixiant is any gas that is none toxic but will kill you if you try to breath 100% of it because it will starve you of Oxygen.
