What is the vapor density of gasoline?

Vapor density is a critical characteristic of substances like gasoline, which informs how they might behave in the environment, particularly in fire and safety scenarios. Gasoline has a vapor density of approximately 3.00 when compared to air. This indicates that gasoline vapors are heavier than air, which means that if released, they will tend to settle in low-lying areas, creating potentially hazardous conditions. Understanding the vapor density of gasoline is essential for firefighters and first responders, as it aids in anticipating the spread of vapors in the event of a leak or spill, thus influencing safety protocols and response strategies.
