As soon as ignited, a chain response need to occur whereby fires can maintain their unique heat from the even more launch of heat Vitality in the whole process of combustion and may propagate, offered You will find a continuous supply of an oxidizer and gas.[57] In the event the oxidizer is oxygen from your bordering air, the existence of the pressure of gravity,[58] or of some identical power caused by acceleration, is important to make convection, which gets rid of combustion products and solutions and brings a offer of oxygen into the fire.
There isn't a solid more than enough attraction amongst the two hydrogen atoms and a person oxygen atom inside of a drinking water molecule and the two oxygen atoms within an oxygen molecule, so the water compound will not split aside and recombine.
Diverse flammable fuels capture fire at diverse temperatures. It will require a specific level of heat Vitality to alter any certain materials into a gas, and much more heat energy to set off the reaction with oxygen.

In microgravity or zero gravity,[72] such as an ecosystem in outer Place, convection not occurs, as well as flame will become spherical, with a bent to be additional blue and a lot more effective (even though it could head out if not moved steadily, as being the CO2 from combustion doesn't disperse as conveniently in microgravity, and tends to smother the flame).
