👉 A recognized fluid is a substance that exhibits properties of both liquids and gases, often found in nature or produced artificially. It has a low viscosity, allowing it to flow easily, like a liquid, yet it can also expand and take the shape of its container, similar to a gas. Examples include water vapor, steam, and certain biological fluids like blood plasma. These fluids are crucial in various natural processes and industrial applications due to their unique properties, such as facilitating heat transfer, transporting nutrients, or enabling chemical reactions.
