How many cubic feet of vapor will one pound of liquid propane (C3H8) expand to?

One pound of liquid propane (C3H8) expands to approximately 8.5 cubic feet of vapor when it evaporates. This expansion is due to the significant difference in density between liquid propane and its gaseous form.

When liquid propane vaporizes, its volume increases dramatically because gases occupy much more space than liquids. Understanding this expansion is crucial for various applications, including safety considerations in storage and handling of propane, as well as for calculations in heating and fuel systems. Therefore, knowing that one pound of liquid propane expands to 8.5 cubic feet of vapor is essential for efficient and safe design and operation in any system that utilizes propane as a fuel source.
