Cryogenic refers to the study and application of materials at extremely low temperatures, typically below -150 degrees Celsius (-238 degrees Fahrenheit). At these temperatures, gases can condense into liquids, and many materials exhibit unique properties. Cryogenics is essential in various fields, including space exploration, medical technology, and superconductivity. In practical terms, cryogenic processes are used to store and transport gases like liquid nitrogen and liquid helium. These substances are crucial for preserving biological samples, cooling superconducting magnets, and enabling advanced scientific research. The technology also plays a role in cryopreservation, which helps preserve cells and tissues for future use.
