Which term describes a liquid that boils at temperatures below -130°F under normal atmospheric pressure?

A liquid that boils at temperatures below -130°F under normal atmospheric pressure is referred to as a cryogenic liquid. Cryogenic liquids are typically associated with the storage and transport of gases in liquid form at extremely low temperatures. These liquids exist at temperatures significantly below the freezing point of water and have specific applications in fields such as aerospace, medicine, and energy.

When a substance is classified as cryogenic, it means that it can exist as a liquid only under conditions of very low temperature and relatively high pressure. This is crucial for processes that require the containment of gases in a liquid state for efficiency and safety. Common examples of cryogenic liquids include liquid nitrogen and liquid helium, both of which are used widely in various scientific and industrial applications.

The other terms do not accurately describe the properties of liquids that boil at such low temperatures. Refrigerants, for instance, are substances used in cooling systems and can be either cryogenic or non-cryogenic, depending on their boiling points. Non-cryogenic liquids have boiling points above -130°F and can be used in standard applications without the extreme conditions that cryogenic liquids require. Liquid gas, on the other hand, generally refers to gases that can exist in a liquid state under pressure and does not specify the
