🔍 Key Concepts

• Flash point vs. ignition temperature – how much energy is needed and what happens at that temperature • Self-sustained combustion – what it means when a fire continues without an outside spark or flame • Basic fire chemistry – fuel, oxygen, and heat forming the fire triangle

💭 Think About

• Which term describes the temperature where a substance will keep burning on its own once it reaches that temperature, without needing a match, spark, or flame to continue? • Which option is about a temperature (not a concentration or range) and specifically about starting and maintaining combustion? • How does the definition of flash point differ from the temperature where a substance actually ignites and burns on its own?

✅ Before You Answer

• Identify which choices describe a temperature and which describe a range or concentration • Recall that flash point is the temperature at which enough vapor is given off to form an ignitable mixture with air, but it still needs an external ignition source • Confirm which term in the choices is defined as the temperature at which a substance will ignite and sustain burning without an external ignition source
