Which fuel distills at a temperature lower than Jet Fuel but higher than Gasoline?

Which fuel distills at a temperature lower than Jet Fuel but higher than Gasoline?

• A. Naptha
• B. Gasoline
• C. Diesel
• D. Jet Fuel

Answer: (A)

The concept being tested is how refinery fractions separate by boiling points. In a distillation column, lighter, smaller molecules boil away at lower temperatures and are collected first, while heavier molecules need higher temperatures to distill. Gasoline is composed of lighter molecules and distills at the lower end of the range, jet fuel consists of heavier molecules and requires higher temperatures, and naptha sits between these two. Its molecules are heavier than those in gasoline but lighter than those in jet fuel, so naptha distills at temperatures between gasoline and jet fuel. That makes naptha the fuel that distills at a temperature lower than jet fuel but higher than gasoline.
