🔍 Key Concepts

• Flash point vs fire point: how are they different in terms of ignition and continuing to burn? • Role of an external spark or flame vs ignition with no external ignition source (autoignition). • Meaning of self-sustained combustion and how it relates to the temperature at which a liquid will keep burning.

💭 Think About

• Which term describes the temperature where vapors will ignite AND continue to burn after the ignition source is removed, not just briefly flash? • Which option specifically involves needing a spark or flame, and which one describes ignition without any external source? • Look at the phrase "lowest temperature" and "self-sustained combustion" together— which standard fire-safety definition matches both parts of that phrase?

✅ Before You Answer

• Verify which choice mentions ignition without any external spark or flame—that one does NOT match the question wording. • Differentiate between the temperature where vapors first flash briefly and the temperature where they continue to burn on their own. • Eliminate any term that refers to the temperature at which a liquid simply changes state to vapor rather than describing ignition/combustion behavior.
