What is ignition temperature of a fluid?

Ignition temperature, also known as the autoignition temperature, is the minimum temperature at which a fluid will spontaneously ignite without an external ignition source, such as a spark or flame. This temperature varies depending on the fluid's composition and environmental conditions. It is a critical parameter in fire safety and chemical engineering, as it helps determine the risk of fire or explosion in various applications. Understanding ignition temperature is essential for the safe handling and storage of flammable materials.
