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

| Petrol | 247–280 °C (477–536 °F) |
| Diesel | 210 °C (410 °F) |
| Phosphorus,white | 34 °C (93 °F) |
