What characterizes a cryogenic container?

A cryogenic container is specifically engineered to maintain substances in a liquid state at extremely low temperatures. This is achieved through advanced insulation techniques that minimize heat transfer and prevent the fluid from boiling off, combined with venting mechanisms that manage pressure buildup as the liquid vaporizes. Cryogenic containers are commonly used for gases like oxygen or nitrogen, where they must remain in liquid form for storage and transport. The focus on preserving the liquid state under low temperature distinguishes cryogenic containers in various industrial applications, especially in healthcare settings for medical gases.

The other options describe different types of containers that do not align with the principles and design features of cryogenic storage. For instance, low-pressure vessels do not necessarily deal with low temperatures or liquids, and atmospheric containers are focused on handling hazardous liquids without the cryogenic aspect. High-pressure tanks generally refer to gases stored at ambient temperatures and are not designed for cryogenic conditions.
