👉 Fluid, in its most basic terms, is a substance that takes the shape of its container while maintaining a constant volume. This unique property arises from the cohesive forces between fluid molecules, which are weaker than those holding solid or liquid particles together. As a result, fluids flow and fill any open space they occupy, whether it's a container or a vacuum. The viscosity of a fluid, a measure of its resistance to flow, also plays a significant role in determining how it behaves under different conditions. For instance, water is less viscous than honey, meaning it flows more easily. Understanding fluid behavior is crucial in various fields, from engineering and physics to meteorology and biology.
