These substances are called flammable.
It suffoctaes the fire by depriving the fire of air which it needs 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.
Fire burn changes the wood chemical.
A chemical burn. Strong acids and strong bases both cause chemical burns.
burn fire and it becomes ashes.
Yes, provided the fire is not too large and is not a chemical fire that can burn without air.
YES, but it's better to say that substances burn, causing fire.
If you burn calcium in a fire, the fire turns to a different color Also any other chemical
Lye
They can start to burn
When we talk about "burning" it generally means a chemical reaction with oxygen from the air, which produces heat. Nuclear scientists and engineers also talk about "burning" or "burnup" of the nuclear fuel, in this case there is no fire or chemical reaction, so perhaps this is what you have in mind.
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.
