👉 A fluid is a substance that takes the shape of its container and flows easily, unlike solids which have a fixed shape and volume. Liquids, the most common type of fluid, consist of molecules that are close together but can move around each other and change position rapidly. This allows them to flow smoothly, filling any space their container can hold without losing their identity. Examples of fluids include water, blood, and oil. Unlike gases, which have much higher kinetic energy and can fill any container regardless of its shape, fluids maintain a distinct volume but can change shape to conform to the boundaries of their container.
