What is the density of propane?

The density of propane is approximately 1.5 kg/m³, which is often rounded to about 1.6 for practical purposes. This means that if you were to take one cubic meter of propane, it would weigh around 1.6 kilograms.

Understanding the density of propane is critical for firefighters, especially when considering its behavior in different environments. Since propane is lighter than water but heavier than air, its density suggests that it will rise and dissipate into the atmosphere when released, rather than pooling on the ground like heavier substances. This knowledge assists firefighters in making strategic decisions about ventilation and controlling flammable gas hazards during firefighting operations.

Other options like 0.5, 2.0, and 3.0 do not accurately reflect propane's density and would not align with the physical properties of the gas. Knowing the correct density helps responders assess risks effectively and implement appropriate safety measures.
