What is the specific gravity of natural gas?

0.51
0.60
1.00
1.52

The correct answer is: 0.60

The specific gravity of natural gas, which is primarily composed of methane, typically ranges between 0.55 and 0.65. The choice of 0.60 falls within this range and accurately reflects the common measurements observed in the industry. Specific gravity is a comparison to air, meaning that a specific gravity less than 1 indicates the gas is lighter than air, which is a characteristic of natural gas. This lighter-than-air property is important for safety and operational considerations, as it influences how natural gas disperses in the event of a leak. The other options provided fall outside the commonly accepted range for natural gas, either representing gas types that are heavier or mistakenly indicating properties not relevant to natural gas. Understanding the specific gravity of natural gas is crucial for gas fitters in ensuring safe installation and handling procedures.
