are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.
Is fire a gas?
“But fire is something else altogether. It is a
chemical reaction that happens in a mixture of gases
.” Simply defined, fire is a chemical reaction in a mixture of incandescent gases, typically luminous with intense heat. But candle flames, wood fires, and propane fires aren’t created equal.
What is the life cycle of fire?
The six elements of the life cycle of fire are described by Dawson Powell in The Mechanics of Fire. These elements are
input heat, fuel, oxygen, proportioning, mixing, and ignition continuity
. All of these elements are essential for both the initiation and continuation of the diffusion flame combustion process.
Can fire exist without oxygen?
A fire cannot burn without oxygen
. … The burning that a star does, then, is a nuclear reaction, and not a chemical one like the fires on Earth (when a candle burns, the atoms themselves remain unchanged: just the molecules are affected).

the visible effect of the process of combustion
– a special type of chemical reaction. It occurs between oxygen in the air and some sort of fuel. … The fuel must be heated to its ignition temperature for combustion to occur. The reaction will keep going as long as there is enough heat, fuel and oxygen.
What causes fire?
Fire is the result of
applying enough heat to a fuel source
, when you’ve got a whole lot of oxygen around. As the atoms in the fuel heat up, they begin to vibrate until they break free of the bonds holding them together and are released as volatile gases. These gases react with oxygen in the surrounding atmosphere.
