Cryogenic Fluids

Cryogenic liquids, substances that have their normal boiling point below about -150 C (or 123 K or -240 F), often exhibit unusual behavior compared to other liquids. Viscosity and other characteristics may change dramatically. For reference some common Normal Boiling Point (NBP) temperatures and densities of cryogenic liquids are included below.


A more detailed description of specific cryogenic liquids can be found at the following links:
