If the vapor density is greater than 1, what will happen to the vapor?

When the vapor density of a substance is greater than 1, it means the vapor is denser than air. This characteristic is crucial in understanding how the vapor will behave in the atmosphere. Since the vapor is heavier than air, it will tend to sink and collect in low-lying areas rather than rising like lighter vapors would. The behavior of vapors with densities greater than 1 poses specific hazards, especially in confined spaces, where they can accumulate and potentially create dangerous situations. Awareness of this property is essential for hazard assessment and response planning in hazmat situations.
