What is the specific gravity of natural gas approximately?

0.90 Specific Gravity
0.50 Specific Gravity
1.50 Specific Gravity
2.00 Specific Gravity

The correct answer is: 1.50 Specific Gravity

The specific gravity of natural gas, which is a crucial measurement for gas fitters, is approximately 0.60 to 0.80 when compared to air. This means that natural gas is lighter than air, which is essential for understanding how the gas behaves in residential and commercial applications. The correct response aligns with typical values reported for natural gas. The concept of specific gravity is important as it influences gas flow, leakage potential, and the design of gas distribution systems. A specific gravity value of 1.50 would imply that the gas is denser than air, which does not represent the physical properties of natural gas correctly. Similarly, values such as 0.90 or 0.50 do not accurately reflect natural gas's characteristics, as they suggest either a heavier or lighter gas than what is typically observed. Understanding the specific gravity helps gas fitters ensure safe installation and effective operation of gas appliances.
