Ignition temperature is the minimum temperature at which a material will burn or explode. It is the temperature at which a mixture of flammable vapor and air would ignite without a spark or flame. The term ignition temperature is also used to describe the temperature of a hot surface that would cause flammable vapors to ignite. Gasoline is the most common flammable liquid and the main cause of injuries among teenage boys. The ignition temperature of gasoline ranges from 530 and 553 K. In addition to ignition temperature, other properties associated with the flammability of a liquid are its flash point, flammable range, and vapor density. The flash point is the temperature at which a flammable liquid vaporizes and is therefore able to ignite. Liquids with a flash point under 40 °C are considered combustible liquids. Gasoline has a flash point of about -45 °C. |
