The auto ignition temperature of a substance is affected by its chemical composition, pressure, concentration in air, and the presence of catalysts or impurities. Higher pressure and sufficient oxygen generally lower the auto ignition temperature, while complex chemical structures increase it. Factors like moisture and particle size also play a role; finely divided particles ignite more easily due to increased surface area. These factors are crucial in fields like fire safety and engine design, where managing ignition risks is essential. If you want to know more about it, then join with us.
