AUTOIGNITION Meaning and
Definition
-
Autoignition is the process by which a substance spontaneously ignites or catches fire without an external ignition source, such as a spark or flame. It occurs when the substance reaches a certain temperature, known as the autoignition temperature, at which it becomes self-igniting.
The autoignition temperature is unique to each substance and refers to the minimum temperature it must reach for autoignition to occur. This temperature is influenced by factors such as the substance's chemical composition, concentration, and physical state. Some materials have relatively low autoignition temperatures, while others require very high temperatures to spontaneously ignite.
During autoignition, the substance undergoes thermal decomposition or oxidation, releasing enough energy to sustain the combustion process without the need for an external heat source. Once ignited, the substance will continue to burn until either it is consumed entirely or the source of heat or fuel is removed.
Autoignition can be a significant concern in industrial settings, where certain materials, such as flammable liquids or gases, can pose a fire hazard due to their low autoignition temperatures. Therefore, it is crucial to understand and mitigate the risk of autoignition by implementing appropriate safety measures, such as maintaining proper storage conditions, controlling temperature, and avoiding potential ignition sources.
Overall, autoignition refers to the self-ignition of a substance when it reaches its minimum temperature for combustion, without requiring an external source of ignition.

Etymology of AUTOIGNITION
The word "autoignition" is derived from the combination of two components: "auto" and "ignition".
The prefix "auto-" comes from the Greek word "autos", meaning "self". In English, "auto-" is commonly used to indicate something related to oneself or self-operating.
The term "ignition" has its roots in the Latin word "ignitionem", which means "a setting on fire". It is derived from the Latin verb "ignire", meaning "to set on fire" or "to burn".
When these two components are combined, "autoignition" essentially conveys the concept of something being ignited or catching fire on its own or spontaneously, without the need for an external spark or flame.
