Q

Which statement is TRUE concerning the "flash point" of a substance?

🔍 Key Concepts

• Flash point vs. ignition (auto-ignition) temperature • Difference between vapor production and continuous burning • How vapors behave just as they are able to be ignited, but may not keep burning on their own

💭 Think About

• Which option best describes the first temperature at which a liquid gives off enough vapor that it can be ignited, even if it might not keep burning afterward? • Which options are actually describing ignition temperature or explosive range, rather than flash point? • Look for the choice that talks about the earliest onset of flammable vapor, not the point where it burns continuously or explodes.

✅ Before You Answer

• Identify which choice refers to auto-ignition (lighting without an outside flame) and rule it out as flash point. • Check which choice describes the condition where vapors will keep burning after ignition; that is not the flash point, but a different temperature (often called fire point). • Confirm that flash point is always below the temperature where the substance will burn on its own without an external flame.
