495° F (232(232° C)
The flash point is the temperature at which a flammable liquid vaporizes and is therefore able to ignite. Liquids with a flash point under 40 °C are considered combustible liquids. Gasoline has a flash point of about -45 °C. The fumes from gasoline are what ignites. They will ignite at any temperature. According to the best sources I could find there are three answers (a … ll apply to gas fumes as stated above). 1.) Flash point -43 F 2.) Ignition Temp -40 both of the above require an external source of ignition. Then ..... Comparison of Auto Ignition Temperature The auto ignition temperature is the temperature at which a fuel will ignite without the need for a spark or flame. In respect to auto ignition temperature LPG, CNG, and LNG are much safer than gasoline or diesel because the auto ignition temperature is much higher. Each fuel should be brought above its Ignition Temperature for starting the combustion process. An appropriate air-fuel ratio is also necessary. The minimum ignition temperature at atmospheric pressure for some substances are: carbon 400 C, gasoline 260 C, hydrogen 580 C, carbon monoxide 610 C, methane 630 C.. 533 K. Ignition temperature is the minimum temperature at which a material will burn or explode. Best Answer: The flash point of gasoline is -45 F. Below that temperature, even with an ignition source, gasoline will not evaporate enough to ignite and burn. (The flash point of a chemical is the lowest temperature where it will evaporate enough fluid to form a combustible concentration of gas. The most commonly known flammable liquid is gasoline. It has a flash point of about -50° F (-65° C). The ignition temperature is about 495° F (232(232° C) [sic], a comparatively low figure..
