Which of the following statements about kerosene and gasoline is true?

The correct answer highlights that kerosene has a higher energy value per unit weight compared to gasoline. This means that when comparing equal weights of the two fuels, kerosene will provide more energy upon combustion than gasoline. This property is particularly advantageous in aviation, where the weight of fuel plays a crucial role in overall aircraft performance and efficiency.

Kerosene's higher energy density per weight is essential for applications like jet fuel, which needs to deliver maximum energy while minimizing weight. In contrast, gasoline, while often heavier in terms of volume, contains less energy per weight unit, making it less efficient for certain applications, especially in aviation.

Understanding this distinction is vital in aeronautics and fuel selection because it impacts not just the range and endurance of aircraft but also the design considerations for propulsion systems and overall mission planning.
