Cryogenic liquids are those which exist at:

Cryogenic liquids are those which exist at:

• A. greater than 32°F
• B. minus 0°F
• C. minus 130°F
• D. minus 110°F

Answer: (C)

Cryogenic liquids are defined by their extremely low temperatures, staying liquid only because they’re kept far below normal ambient conditions. In this safety framework, the practical threshold used to classify something as cryogenic is around minus 130 degrees Fahrenheit. That makes minus 130°F the correct choice, because it sits at the defined boundary for cryogenic liquids in this material. The other temperatures are not cold enough to be considered cryogenic within this context. This classification matters because cryogenic liquids require special handling, storage, and precautions due to the severe cold, potential for rapid vaporization, and related hazards.
