🔍 Key Concepts

• Difference between flash point and fire point in fuel safety • Meaning of self-sustaining combustion • Role of an external ignition source in starting vs continuing burning

💭 Think About

• Ask yourself: At which temperature does the fuel just begin to give off enough vapor to ignite momentarily, and at which temperature will it continue to burn on its own after being lit? • Which of these terms describes ignition with no external flame or spark present, and which involves a flame or spark starting the burn? • Which definition focuses on the start of visible flame, and which focuses on continuous burning after ignition?

✅ Before You Answer

• Be sure you know that flash point involves ignition only while the ignition source is applied. • Remember that self-sustaining combustion means the fuel keeps burning after the ignition source is removed. • Check which choice best matches: "lowest temperature" + "combustion continues on its own once lit in the presence of an ignition source."
