Which chart is used to verify propane's boiling point according to the data?

• A. Propane boils at -40F; use chart on page 120.
• B. Propane boils at -50F; use chart on page 145.
• C. Propane boils at -44F; use chart on page 145.
• D. Propane boils at -44F; use chart on page 120.

Answer: (C)

When verifying a propane boiling point, you must pair the data value with the chart that actually lists propane’s data at standard pressure. Propane’s boiling point at one atmosphere is -44°F, so the correct reference is the statement that states -44°F and uses the chart that contains propane’s data at that temperature. The other options give an incorrect boiling point or point to a chart that doesn’t match propane’s data, so they wouldn’t allow a proper verification.
