Ignition temperature is the minimum temperature at which a material will ignite and start to burn without an external flame or spark. This temperature varies for different substances, depending on their chemical properties and physical state. For example, wood has a higher ignition temperature than paper, meaning it requires more heat to catch fire. Understanding ignition temperature is crucial for fire safety and prevention. It helps in determining safe storage conditions for flammable materials, such as fuels and chemicals. By knowing the ignition temperatures, industries can implement measures to reduce the risk of accidental fires.
