Not by itself, it requires an ignition source.
Fuel, oxygen and an ignition source
removing the fuel or source of ignition.
there isn't an actual chemical to start fire. all you need is an ignition source, oxygen, and a fuel source (such as wood)
Fuel, heat, oxygen...obviously.
There is what is known as a "fire/combustion" triangle, which has the three components necessary for fire: oxygen, fuel, heat
Fuel, Oxygen and a heat source. Fuel, Oxygen and heat are everywhere why is the whole earth not on fire? because it is not Heat but a source of ignition that is needed.
The fire triangle is a simple model that illustrates the three components needed for fire to occur: heat, fuel, and oxygen. When these three elements are present in the right proportions, a fire can start and continue to burn. Removing one of these components can help extinguish a fire.
Kind of an unfair question. Fire is composed of fuel source, an oxidizer, heat, and an ignition source. The fuels are to numerous to list, but the short list is solids, gases, and liquids. If you really need to impress people, tell them that the 4 things above are known as the "Fire tetrahedron". Good for trivia night!
An ignition source, fuel and oxygen
Gas does not spontaneously explode. There has to be an ignition source, as when lighting a fire. The ignition source would have to be a spark from a fire. Gasoline in itself is not an explosive device that when agitated will explode. The myth that gasoline explodes upon agitation is false, and gas only explodes when it is ignited in some sort of way by a fire, or constant source of extreme heat.
It is the lowest temperature at which a flammable liquid can receive an ignition source and be ignitable. However, once the ignition source is removed, the flammable nature may cease and the flame stop. At temperatures slightly higher, it is when an ignition source is introduced and the ignition source is removed that the flammable liquid continues to burn regardless of the ignition source. The lowest temperature at which a flammable liquid (e.g. gasoline) becomes capable of catching fire in the air. The correct term applied to non-liquids is the autoignition temperature or kindling point.
