👉 A frozen fluid, also known as a cryogenic liquid, is a substance that exists in a solid state at temperatures significantly below its boiling point, typically below -150°C (-238°F). These liquids are formed when a substance is cooled to its freezing point, causing the molecules to lose kinetic energy and arrange themselves into a rigid, ordered structure. Common examples include liquid nitrogen (-196°C) and liquid helium (-269°C), which are used in various scientific, medical, and industrial applications due to their unique properties such as extreme cold and low viscosity.
