What is the specific gravity of propane gas?

The specific gravity of a gas is a measure of its density compared to the density of air. For propane gas specifically, the specific gravity is approximately 0. Propane is lighter than air, which is why its specific gravity value is less than 1.

A specific gravity of 0.78 indicates that propane is less dense than the surrounding air. This means that under standard conditions, propane will rise into the atmosphere when released. Understanding the specific gravity of propane is essential for safety and management in applications involving gas storage, transport, and usage, as it informs how propane behaves in the environment.

The other values given for specific gravity (1.52, 1.25) suggest that those gases would be denser than air, which is not the case for propane. These values are indicative of heavier gases or compounds. Thus, the correct answer of 0.78 accurately represents the properties of propane and is crucial for practical applications.
