👉 A change fluid is a type of liquid that can flow and adapt to different shapes or surfaces, much like how water moves through porous materials or how certain oils can fill and conform to irregularities. This fluid exhibits properties of both liquids and gases, allowing it to spread easily, penetrate tight spaces, and conform to the contours of objects. It's often used in applications like lubrication, where it reduces friction between moving parts, or in medical devices for minimally invasive procedures. The key characteristic is its ability to change form and flow, making it versatile in various industrial and scientific contexts.
