the self ignition auto  ignition temperature  lowest temperature  at which   a fuel  such as  petrol or  diesel  spontaneously ignites in normal  atmosphere without an external  source  of ignites ,  such as  flame or  spark

the autoignition temperature or kindling point of a substance is the lowest temperature at which it is spontaneously ignities in normal atmosper without an external sources of ignition such as a flame are speak.

THE auto ignition or kinding point of a substance is the lowest at which it spontainesly ignites in normal atmosphere without an external source of ignition such as a flame or a spark this temperature is required to supply a activation energy needed for combusion 
thank you

ignition temperature is the temperature as which something catches fire and burns on its own.the ignition temperature of paper is 451 degrees fahrenheit is 223 degrees celcious .

 The Self Ignition auto ignition temperature is lowest temperature at which a fuel such as petrol or diesel spontaneously ignites in normal atmosphere without an external source of ignition, such as a flame or spark.

the most commonly known flammable liquid is gasoline .it as

* the most commonly known flammable liquid is gasoline .
* it has a flash point of of about -50 degere F (-65degere c) the ignition temperature is about 459degere F

the auto ignition temperature or kindly point of a substance is the lowest  which it spontaneously in   ignites in normal atmosphere without an  external source of ignition, such as a flame or spark.

Ashwini and rogini the most commonly known flammable liquid is gasoline . *it has a flash point of about -50degere (-65degere c) the ignition temperature is about 495degere F (232degere c){sic} a comparatively low figure.

the minimum temperature needed to ignite wood is 180 degrees Celsius of 356 degrees fahrenheit the amount of time of exposure varies due to the type of wood long leaf wood has the fastest ignition time at thes temperature taking about 14 minutes to ignite Oct 17 2017

The auto ignition temperature or kindling point of a substance is the lowest temperature   at which it spontaneously ignites in normal atmosphere without an external source. THIS TEMPERATURE IS REQUIRED TO SUPPLY THE ACTIVATION ENERGY NEEDED FOR COMBUSTION.
