👉 Fluid, often used to describe liquids and gases, is a state of matter characterized by its ability to flow and take the shape of its container. Liquids have a definite volume but no definite shape, meaning they fill any space they are placed in while maintaining a constant density. Gases, on the other hand, have no definite volume or shape, expanding to fill their container completely and taking on any shape imposed upon them. Both fluids exhibit viscosity, which is a measure of their resistance to flow, and they can exhibit complex behaviors like surface tension and capillary action. Understanding fluid dynamics is crucial in various fields, including physics, engineering, and meteorology.
