What is the specific gravity of the natural gas being used in the provided scenarios?

To determine the specific gravity of natural gas in various scenarios, it's important to understand the concept of specific gravity itself. Specific gravity is a measure of the density of a substance compared to the density of air. For natural gas, which primarily consists of methane, the specific gravity is typically close to 0.60 when measured under standard conditions.

This value indicates that natural gas is lighter than air, which is a crucial characteristic that influences how it behaves in different conditions. For example, since natural gas rises and disperses rapidly when released, it diminishes the risk of accumulation and potential hazards.

Recognizing the standard specific gravity of natural gas helps in calculating the proper ventilation, combustion efficiency, and safety measures required during its use or transportation. By identifying the specific gravity at 0.60 as the answer, we align with the typical characteristics of natural gas, indicating that this scenario is reflective of typical gas compositions observed in practice.
