What is the specific gravity of propane vapor compared to air?

• A. 1.2
• B. 1.0
• C. 1.5
• D. 1.8

Answer: (C)

The correct answer is that the specific gravity of propane vapor compared to air is 1.5. Specific gravity is a comparison of the density of a substance to the density of another substance, in this case, propane vapor to air. When the specific gravity of a vapor is greater than 1, it indicates that the vapor is heavier than air, which is important information for safety and handling procedures. Propane vapor, with a specific gravity of approximately 1.5, is thus heavier than air, meaning it can accumulate in low-lying areas, posing a risk of explosion or asphyxiation if not managed properly. Understanding the specific gravity of propane is crucial for safe dispensing and storage practices, as it influences how propane vapors will behave in the environment.
