Statement: “All the commercial liquid fuels are derived from natural petroleum (crude oil).”
Choose whether the statement is correct or incorrect (as per conventional thermal-engineering classification).
Difficulty: Easy
Correct Answer: Agree (the statement is correct)
Explanation:
Concept/Approach
Conventional commercial liquid fuels (gasoline/petrol, kerosene, diesel, furnace oil, LDO/HFO) are petroleum distillates or blends from crude-oil refining.
Though alternative liquids like ethanol exist, classic textbooks typically classify commercial liquid fuels as petroleum derived.
Final Answer Agree — in the usual engineering classification, commercial liquid fuels are derived from crude oil.
