Difficulty: Easy
Correct Answer: Liquefied petroleum gas
Explanation:
Introduction / Context:LPG is a widely used fuel comprising mainly propane and butane (and their mixtures). The correct standardized expansion is important in technical documentation, labeling, and regulations.Given Data / Assumptions:
Concept / Approach:Standards and safety codes (transport, storage, MSDS) consistently use “Liquefied petroleum gas.” Note the spelling “Liquefied,” not “Liquified,” and “petroleum,” not “petrol.” The term reflects gas that has been liquefied by compression/cooling for storage and transport.Step-by-Step Solution:
1) Eliminate “liquid petrol gas”: “petrol” denotes gasoline, not LPG.2) Eliminate misspelling “liquified.”3) Choose “Liquefied petroleum gas.”Verification / Alternative check:Product datasheets and regulatory references consistently adopt “Liquefied petroleum gas (LPG).”
Why Other Options Are Wrong:
Liquid petroleum gas: not the standard phrasing; emphasis is on the liquefaction process.Liquified petrol gas: incorrect spelling and “petrol” is wrong substance.Liquid petrol gas: incorrect terminology for this mixture.Common Pitfalls:Confusing gasoline (“petrol”) with LPG constituents; propane/butane are distinct from gasoline fractions.
Final Answer:Liquefied petroleum gas
