Define of ignition temperature?

Answer..The lowest temperature at which a substance catches fire is called ignition temperature.​

Answer 1

Answer:

In chemistry, the autoignition temperature or kindling point of a substance is the lowest temperature in which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark. This temperature is required to supply the activation energy needed for combustion.

Answer 2

Answer:

The lowest temperature at which a substance catches fire and undergoes combustion liberating heat and light is called ignition temperature. In other words it is the minimum temperature at which a combustible substance such as air or gas, must be heated up prior to burning in the absence of any source of the heat.
