When propane changes from a liquid to a gas, it experiences a significant increase in volume due to the phase change. Specifically, propane can expand up to 270 times its original liquid volume when it is converted to a gaseous state. This substantial expansion is a result of the difference in density between the liquid and gas phases; liquids are much denser than gases, so when the propane liquid vaporizes, it occupies a much larger volume as a gas.

The 270 times expansion is a critical piece of knowledge in applications where propane is used as fuel, particularly in settings that require careful handling and storage. Understanding this expansion factor is essential for safety and proper design in systems that utilize propane, as it illustrates the need for adequate ventilation and containment to prevent pressure buildup and potential hazards. This factor is particularly important in industries and situations where propane is stored under pressure and may be released, emphasizing proper engineering practices and safety protocols.
