It is the lowest temperature at which substance catches fire

Substance cannot catch fire unless it reaches its ignition temperature

Example - Ignition temperature of Diesel is 210 degree celsius

It means it does not catch fire until it reaches 210 degree celsius

Note

Ignition Temperature  is different for different products

Example

Ignition temperature of Diesel is 210 degree celsius but iron is 1315 degree celsius

It means diesel catches fire more easily as compared to iron

 Substance Ignition Temperature Petrol 247–280 °C (477–536 °F) Diesel 210 °C (410 °F) Phosphorus,white 34 °C (93 °F) Ethanol 365 °C (689 °F) Iron 1,315 °C (2,399 °F) Paper 218–246 °C (424–475 °F) Lead 850 °C (1,560 °F) Leather 200–212 °C (392–414 °F) Hydrogen 536 °C (997 °F) Magnesium 473 °C (883 °F) Tin 940 °C (1,720 °F)
