What is the lower flammability limit of propane in air?

1.5%
2.15%
3.0%
4.0%

The correct answer is: 2.15%

The lower flammability limit of propane in air is indeed approximately 2.15%. This value indicates the minimum concentration of propane in air required to sustain combustion. Below this concentration, there are not enough propane molecules in the mixture to propagate a flame. Understanding the specific flammability limits is critical for safety in various contexts, such as industrial applications, storage, and handling of propane. It also helps in assessing the potential hazards associated with using propane as a fuel. Knowing that the lower limit is 2.15% allows professionals to make informed decisions about ventilation and leak detection to prevent dangerous conditions that could lead to fires or explosions.
