What is the specific gravity of natural gas?

The specific gravity of natural gas is a crucial property in HVAC applications, as it helps determine how the gas will behave in various environments and systems. The specific gravity of natural gas is typically around 0.60 when compared to air, which has a specific gravity of 1.0. This means that natural gas is lighter than air; thus, it will rise in the atmosphere.

Knowing this property is essential for safety and efficiency within HVAC systems, particularly when dealing with venting and gas detection. A specific gravity of 0.60 indicates that any leaks in a system will lead to the gas dispersing upward, which influences how systems are designed and how technicians respond to gas-related situations.

The other choices reflect values that do not accurately represent the specific gravity of natural gas, leading to potential misunderstandings regarding its behavior in different situations. Understanding the correct value of 0.60 aids HVAC professionals in ensuring safe installations and handling of systems that utilize natural gas.
