Power alcohol as compared to straight run gasoline has lower ________________?
Correct answer: A. Calorific value
- A. Calorific value
- B. Octane number
- C. Specific gravity
- D. Viscosity
Explanation
Alcohol contains oxygen in its molecule and releases less heat per kilogram than hydrocarbon gasoline, so its calorific value is lower. Its higher octane number is an advantage, not the property that decreases.
