Which term describes a very low bode temperature?

The term "cryogenic" is used to describe extremely low temperatures, typically below -150 degrees Celsius (-238 degrees Fahrenheit). It comes from the Greek words "cryos" (cold) and "genes" (producing), denoting the production or study of very cold temperatures. Cryogenic temperatures are often achieved through the use of specialized refrigeration techniques, such as liquid nitrogen or helium, and are commonly employed in scientific research, engineering, and various industrial processes.
