Question

what is ignition temperature explain with example and practical activity​

Answer 1

IGNITION TEMPERATURE : It means that a substance is the lowest temperature at which it spontaneously ignites in normal atmosphere without an external source of ignition. » BEST EXAMPLE : Candle flame & Fire

Answer 2

Ignition temperature is the minimum temperature to which a combustible substance must be heated, before it catches fire. Therefore, we see that a combustible substance cannot catch fire as long as its temperature is lower than its ignition temperature e.g. Ignition temperature of phosphorus is 35 °C.
