What is the relative density of natural gas compared to air?

The relative density of natural gas compared to air is an important characteristic that plays a role in its behavior in various applications, such as combustion and ventilation. The relative density is calculated by comparing the density of a gas to the density of air at the same temperature and pressure.

In the case of natural gas, the average relative density is typically around 0.55 to 0.65, depending on its specific composition. This means that natural gas is lighter than air, allowing it to rise and disperse in the atmosphere. This characteristic is crucial for safety, as it helps to prevent the accumulation of gas in low-lying areas, which could lead to dangerous situations such as explosions or asphyxiation.

The provided answer indicates a relative density of 0.62, which falls within the expected range for natural gas. This density underlines the fact that natural gas is indeed less dense than air, corroborating its behavior when released into the atmosphere. Understanding this property is vital for gas technicians when considering installation, ventilation, and safety protocols in the use of natural gas.
