What is the specific gravity of oxygen?

The specific gravity of a substance is a measure of its density compared to the density of water. In the case of oxygen, its specific gravity is defined based on how it compares to air. The specific gravity of oxygen at standard conditions is approximately 1.0. This means that oxygen has a density that is about the same as that of air when compared to water.

Understanding this concept is crucial, especially in mine ventilation, because it helps in evaluating how gases behave within the mine environment. The specific gravity of gases is essential for predicting how they will mix, disperse, and rise or settle in various atmospheric conditions. This knowledge aids in ensuring the safety of workers and effective ventilation strategies in mining operations.
