Propane is stored and transported as a liquid.

• A. True
• B. False
• C. It depends on temperature
• D. Not sure

Answer: (A)

Propane is kept in a liquid form inside pressurized containers, which is why it’s stored and transported as a liquid. Its boiling point is about -42°C, so at room temperature it will remain a liquid only if it’s under enough pressure in a sturdy vessel. Those tanks and cylinders are designed to maintain that pressure, keeping propane as a liquid for efficient transport. When you release it, the liquid absorbs heat and boils into a gas, which is what actually burns for heating or cooking. So the way propane is handled in the real world relies on maintaining pressure to keep it liquid, not on the ambient temperature alone.
