Which gas has a specific gravity of 1.52?

The specific gravity of a gas is a measure of its density compared to air, which has a specific gravity of 1.0. A gas with a specific gravity of 1.52 is heavier than air, meaning it will tend to sink in the atmosphere. Propane gas, which has a specific gravity of approximately 1.52, confirms this characteristic. This higher specific gravity indicates that propane is not only denser than air but also contributes to potential safety concerns in confined spaces, as any leaks would cause the gas to accumulate at lower levels.

In comparison, natural gas (primarily methane) has a specific gravity of around 0.6, which is lighter than air. Butane typically has a specific gravity ranging from about 2.0 to 2.5, making it significantly heavier than propane and also heavier than air. Ethane has a specific gravity of about 1.04, which is closer to that of air but still supports the fact that propane is the gas with the specific gravity of 1.52. This distinction is crucial, especially for applications concerning gas safety and management.
