Definition

  1. adj. relating to or involving the production or use of very low temperatures

  2. adj. (of a substance) requiring or involving storage at extremely low temperatures

Structure
cryo <cold, freezing (from Greek *kryos*)>gen <produce, generate (from Greek *-genēs*)>ic <adjective suffix>
Etymology

The word cryogenic combines Greek roots to describe the science of extreme cold. Cryo- derives from kryos (frost, icy cold), while -genic comes from -genēs (producing or generated by). The suffix -ic turns it into an adjective. Historically, the term emerged in the late 19th century alongside advancements in liquefying gases like oxygen and nitrogen, where "producing cold" became a key scientific focus.

Examples

  1. Cryogenic storage preserves biological samples at temperatures below -150°C.

  2. The rocket uses cryogenic fuel to maximize efficiency.

  3. Researchers study cryogenic fluids to improve superconductivity.

  4. Cryogenic freezing is a controversial method for preserving human bodies.

  5. The lab specializes in cryogenic engineering for medical applications.
