Why does flame require air to burn?
fire needs oxygen to burn, because fire is a chemical reaction that needs oxygen. the fire triangle is what fire needs to burn and is this- heat, fuel, and oxygen.
Can you freeze fire?
Fire needs air to burn. It is impossible to freeze fire!
Does fire need air to breathe?
Fire needs oxygen to burn.
Why cant a match burn on the moon?
>>>MoonBecause there is no oxygen, fire needs air to burn.
How does fire get extinguished through a dry chemical used in fire extinguishers?
It suffoctaes the fire by depriving the fire of air which it needs to burn.
Why can not we lite a fire on the Moon?
For a fire to burn the fuel making the fire has to combine with Oxygen from the Air. As there is no Air on the Moon, it is impossible for a fire to burn on the Moon.
What experiment could you do to prove that oxygen is needed for burnig?
simply cover a burning candle with a glass to cut off the air, then the candle will burn out
What percentage must oxygen be for a fire to ignite and burn?
Regular air in the environment is about 21% oxygen. A fire only needs about 16% oxygen to catch and burn. See http://www.bradford-co-fla.org/scvfd/fire_information.html
How air helps in burning explain with diagram?
A fire needs oxygen to burn. A fire in an enclosed space will go out if not enough oxygen is present to keep the fire going. A diagram of this type would show the air flow moving toward a fire instead of away from it.
In general what are dry chemical fire works with extinguishers designed to do?
Fire needs three things to burn: fuel, oxygen, and heat. Take away one or more of those three things in sufficient quantities, and the fire can no longer burn..A dry chemical fire extinguisher sprays a noncombustible, air resistant layer of foam designed to cover the fire's fuel source. When the fuel source (wood, oil, cloth, etc.) is completely and properly smothered, the expelled dry chemical foam isolates the fuel from the surrounding air, and thereby starves the fire of the oxygen it needs to burn.

How you use nitrogen gas to control fire in mine?
A fire needs oxygen to burn. Air contains oxygen. So passing in nitrogen stops incoming air refuelling the fire. Have to be careful if there are trapped people who of course need to take in oxygen as they breathe.
