What is a cryogenic fluid?

A cryogenic fluid is identified as a fluid that has a boiling point lower than -130 °F at standard pressure. This definition is essential because cryogenic fluids are characterized by their extremely low temperatures, which allow them to exist in gaseous form at higher temperatures but can transition to a liquid state at significantly lower temperatures. These fluids are commonly used in various applications, including medicine, aerospace, and research, due to their unique properties, such as being capable of deep cooling and facilitating the transport and storage of gases like oxygen and nitrogen.

Understanding this definition helps clarify the role and significance of cryogenic fluids in different industries and scientific applications, where maintaining low temperatures is crucial to ensure the stability of certain materials or substances.
