A specialized intermodal tank container carrying refrigerated liquid gases such as argon, oxygen, or helium would be an example of which type?

• A. Intermodal freight containers
• B. Cryogenic intermodal tanks
• C. Non-pressurized railcar
• D. Dry box

Answer: (B)

The key idea is recognizing which container is built to carry ultra-cold liquids. Cryogenic intermodal tanks are designed to transport refrigerated liquids at very low temperatures across ships, trains, and trucks. They use vacuum-insulated double walls and pressure-relief systems to maintain the extreme cold and safe containment, which is essential for gases like argon, oxygen, and helium. Standard intermodal freight containers (dry boxes) are not insulated for cryogenic temperatures, and a non-pressurized railcar doesn’t provide the required insulation and temperature control for these liquids. That’s why this is the correct type for carrying those refrigerated gases.
