What is the boiling point of propane and what reference should be used to verify it?

• A. Propane boils at 0F; use chart on page 145
• B. Propane boils at -44F; use chart on page 145
• C. Propane boils at -100F; use chart on page 145
• D. Propane boils at -44F; use chart on page 120

Answer: (B)

Propane’s boiling point is the temperature at which the liquid turns to gas at standard pressure. For propane, that point is about -42°C, which is roughly -44°F. In practical terms, this means propane will vaporize into gas as temperatures rise toward that range, a key consideration when handling and testing tanks and regulators. The correct choice states -44°F and says to verify it using the chart on page 145. That aligns with common reference values used in propane materials and matches the specified source for validation in this material. The other options propose temperature values that don’t match the standard boiling point at normal pressure, and one would direct you to a different chart page, which isn’t the appropriate reference for this verification.
