A cryogenic liquid tank will have which feature?

• A. A a double shell with insulation
• B. B an enclosed dome
• C. C a single uninsulated shell
• D. D fittings visible on top of the tank car

Answer: (A)

Cryogenic liquids must be kept at extremely low temperatures, so the tank is built to minimize heat entering the container. The key feature is a double-walled design with insulation between the inner vessel and the outer shell, often with a vacuum gap. This setup dramatically reduces heat transfer by conduction, convection, and radiation, keeping the liquid cold and reducing boil-off. That’s why the double shell with insulation is the best answer. An enclosed dome or a single uninsulated shell wouldn’t provide the necessary protection against heat, and visible fittings on top aren’t what defines a cryogenic tank.
