Question 1573Deck General70% to pass
Compared to air, the weight of liquefied petroleum gas vapors are which of the following?
AI Explanation
The correct answer is B) heavier.
Liquefied petroleum gas (LPG) vapors are heavier than air. This is because LPG is denser than air, with a specific gravity of around 1.5 to 2.0 depending on the gas composition. Compared to air, which has a specific gravity of 1.0, the LPG vapors are heavier and will sink rather than rise like air. This property makes LPG prone to pooling in low-lying areas, which is an important safety consideration for its handling and storage.
The other options are incorrect - the weight of LPG vapors is not variable (A), nor is it the same as air (D), as it is clearly heavier.
