The autoignition temperature of carbon disulfide is below 100 �C ( 212 �F ), so objects such as steam pipes, light bulbs, hotplates and recently extinguished bunsen burners are able to ignite its vapours.

Diesel is suitable for use in a compressed until it has been heated above the autoignition temperature of the fuel, which is then injected as a high-pressure spray, keeping the fuel-air mix within flammable limits.

:: ( awesome video, by the way ! ) With the caution that since there isn't any convective transfer of heat away from the once-burning match, it will take some time to cool below its autoignition temperature.

My gut feeling would be to say the one with the lowest flashpoint / autoignition temperature, which seems to be in agreement with the Wikipedia article on flammability ( Sorry the link looks external, I was having trouble with the internal link feature)

Plutonium chips can spontaneously ignite; the mechanism involves formation of Pu 2 O 3 layer, which then rapidly oxidizes to PuO 2, and the liberated heat is sufficient to bring the small particles with low thermal mass to autoignition temperature ( about 500 �C ).

As to " why " something may spontaneously combust, the process is complex; concepts like Flash point, Fire point, and Autoignition temperature all come into play .-- 32 " "'12 : 18, 8 August 2011 ( UTC)

The amount of the stabilizer depletes with time; remaining content of less than 0.5 % ( with initial 2 % content ) requires increased surveillance of the munition, with less than 0.2 % warranting immediate disposal, as the depletion of the stabilizer may lead to autoignition of the propellant.

:The autoignition temperature is just the lowest temperature at which a flammable mixture of methane and air will start to burn ( no spark required . ) Once the gas starts to burn, it heats up rapidly and reaches much higher temperatures . talk ) 19 : 51, 26 May 2006 ( UTC)

"' Spontaneous combustion "'or "'spontaneous ignition "'is a type of combustion which occurs by self-heating ( increase in temperature due to exothermic internal reactions ), followed by thermal runaway ( self heating which rapidly accelerates to high temperatures ) and finally, autoignition.

Breathing fire would be easier : there are plenty of animals that secrete and spit substances, so it would simply be a matter of changing the chemicals to a pair of hypergolic chemicals, or to a substance with a low autoignition temperature .-- Carnildo 22 : 59, 27 March 2007 ( UTC)
