Answer 2

A cryogenist is a scientist who specializes in the study of how materials behave at very low temperatures, typically below -150°C. They work with cryogenic liquids like liquid nitrogen and helium to study properties such as superconductivity and superfluidity. Their research has applications in fields like medicine, physics, and engineering.
