Final answer:
A tube module intermodal container (option b) is designed to hold high-pressure gases at 3,000psi or higher, suitable for the specialized transportation and storage of such gases. They have a high safety factor to withstand pressures significantly above the operating pressure.
Step-by-step explanation:
An intermodal container that is capable of holding high-pressure gases at 3,000psi or higher is a tube module intermodal container.
High-pressure gases need to be stored in specialized containers to ensure safety and structural integrity under extreme pressures. A cryogenic intermodal tank is used for liquids that are turned into gases at very low temperatures, not high-pressure gases at room temperature. A pressurized intermodal tank refers to containers that hold gases at increased pressure but typically at lower pressures than 3,000psi. Nonpressurized intermodal tanks are for transporting substances that do not require pressure.
Tube modules, however, are designed specifically for the transportation and storage of high-pressure gases. Similar to the example of gas storage at high pressure at room temperature in a metal cylinder, tube modules are engineered to withstand very high pressures, often much greater than the operating pressure to ensure a high margin of safety.
