👉 A fluid is a substance that can flow or change shape without breaking into pieces, exhibiting characteristics of both liquids and gases. Unlike solids, which maintain a fixed shape and volume, fluids adapt to their container's shape, allowing them to fill any space. They also have a relatively low viscosity, meaning they can flow easily. Examples include water, air, and oils. This unique property of flowing yet maintaining a cohesive structure makes fluids versatile in various natural and industrial processes.
