How many times does liquid propane expand when it changes to a vapor state?

When liquid propane changes to a vapor state, it expands significantly, with the expansion factor typically being about 270 times. This means that one gallon of liquid propane can produce around 270 gallons of propane vapor at atmospheric pressure and temperature. Understanding this concept is crucial for anyone working with propane as it has important implications for storage, handling, and safety procedures.

Knowing the expansion ratio helps in designing systems that handle propane, ensuring that there are proper safety measures in place to contain the vapor. For example, regulators and pressure relief valves must be calibrated to accommodate this rapid expansion, preventing any potential hazards.

The other options do not accurately reflect the expansion ratio of propane, as the commonly accepted factor is consistently around 270 times. Recognizing this correct value is essential for effective calculations and safety assessments in the LP gas industry.
