At 60°F (15.5°C), how many cubic feet of gas does a pound of propane produce?

4.50 cubic feet
6.20 cubic feet
8.50 cubic feet
10.00 cubic feet

The correct answer is: 8.50 cubic feet

The correct answer is based on the thermodynamic properties of propane and its behavior when converted into gas. At a temperature of 60°F (15.5°C), one pound of propane produces approximately 8.50 cubic feet of gas. This value is derived from the definition and properties of propane as a gas, where one pound is vaporized and expanded under standard conditions. Understanding the characteristics of propane, including its specific weight and the conditions that affect its gas volume, is essential for gas fitting professionals. When propane is heated or in a gaseous state, environmental factors, such as temperature and pressure, play a crucial role in determining the volume of gas produced from a certain weight. At the specified temperature of 60°F, propane maintains a volume expansion that is consistent with these properties. Thus, knowing that one pound of propane at this temperature generates about 8.50 cubic feet of gas is crucial for calculations involving gas supply, system sizing, and ensuring the efficiency of propane applications.
