Q

Which is the flammable limit range of Diesel Oil mixed with air?

🔍 Key Concepts

• Lower flammable limit (LFL) and upper flammable limit (UFL) for diesel vapor in air • How diesel’s volatility compares to gasoline (petrol) and heavy fuel oil • Typical flammable range of common hydrocarbon fuels

💭 Think About

• Think about whether diesel is more or less volatile than gasoline and how that affects the width of its flammable range in air • Compare each choice to what you would expect for a relatively low-volatility hydrocarbon fuel • Eliminate any option that looks more like the flammable range for gasoline rather than for diesel

✅ Before You Answer

• Check which range looks relatively narrow and toward the lower concentration side, consistent with diesel’s lower volatility • Make sure the lower limit (first number) is realistic for a fuel that does not readily form vapor at normal temperatures • Verify that the upper limit (second number) is not excessively high compared to typical hydrocarbon UFL values (usually under about 15% by volume)
