Dewar containers are designed to hold which type of liquids?

Dewar containers are designed to hold which type of liquids?

• A. Flammable liquids
• B. Nonflammable liquids
• C. Cryogenic liquids
• D. Corrosive liquids

Answer: (C)

The main idea here is that Dewar containers are built to store extremely cold liquids—cryogenic liquids. Their design features a double-wall with a vacuum insulation layer and a narrow neck, which together minimize heat transfer into the container. This keeps the liquefied gases at very low temperatures and reduces boil-off, making safe storage possible for substances like liquid nitrogen, liquid helium, and liquid oxygen. The emphasis is on maintaining low temperatures, not on whether the liquid is flammable, nonflammable, or corrosive, which is why cryogenic liquids are the best fit for this type of container.
