🔍 Key Concepts

• Flash point: the lowest temperature at which a liquid gives off enough vapor to ignite momentarily when given an ignition source • The general volatility of different petroleum products: lighter vs heavier oils • How heavier residual products (like asphalt, road oils) compare in volatility to lighter distillates (like light fuel oils)

💭 Think About

• Rank the listed products from lightest (most volatile) to heaviest (least volatile). Which one would you expect to ignite at the lowest temperature? • Think about which of these products you might see giving off flammable vapors at normal ambient temperatures versus only at very high temperatures. • If a product is used as a residue or paving material, what does that suggest about its flash point compared to products used as fuels?

✅ Before You Answer

• Identify which option represents the lightest distillate fuel among the choices. • Eliminate products that are typically very viscous or solid at room temperature, as these generally have higher flash points. • Before choosing, make sure your selection is the one most commonly associated with readily ignitable vapors rather than mainly used as a heavy residue or lubricant.
