A high-pressure intermodal tank is commonly used to transport __________.

A high-pressure intermodal tank is specifically designed for the transport of liquefied gases. These tanks are engineered to withstand the high pressures required to keep gases in liquid form, making them suitable for various substances, including propane, butane, and ammonia. The ability to maintain the necessary pressure is crucial, as it allows for the safe and efficient transport of these hazardous materials without the risk of them escaping into the atmosphere.

The design of these tanks typically includes features to prevent leaks and ensure safety during transit. Intermodal tanks can be moved via different modes of transportation, such as trucks, trains, and ships, which adds flexibility and convenience in transporting these materials across various distances.

Other options like solid waste, perishable goods, and non-hazardous materials are typically not transported using high-pressure intermodal tanks due to their different storage requirements and the lack of necessity for high-pressure containment. Thus, the focus on liquefied gases accurately reflects the purpose and design intent of high-pressure intermodal tanks.
