What is a compressed gas container?

A compressed gas container is defined as a pressure vessel that holds gases at pressures exceeding one atmosphere. This means that these containers are specifically designed to maintain and safely contain gases under high-pressure conditions, which is critical for various applications, including medical uses, industrial processes, and chemical storage.

When gases are stored at such elevated pressures, they can reduce in volume, allowing for efficient storage and transportation. The design of these containers includes reinforced materials and safety features to handle these pressures securely, minimizing the risk of rupture or explosion.

The other options do not accurately describe a compressed gas container. Containers designed for holding liquids under low pressure or exclusively for liquefied gases do not encompass the requirements necessary for storing gases under high pressure. Likewise, a tank used for storing solid materials is unrelated to the specific characteristics and functions associated with compressed gas containers.
