👉 Fluid, often referring to liquids or gases, is a state of matter characterized by several key factors. Primarily, fluids have no fixed shape but can adapt to the shape of their container, a property known as compressibility. They also exhibit viscosity, which is the internal friction that resists flow, determining how easily a fluid moves. Fluids have high energy density, meaning they can store a lot of energy per unit volume, and they flow spontaneously from areas of higher pressure to lower pressure. Additionally, fluids are homogeneous and isotropic, meaning their properties are uniform throughout and in all directions. These factors collectively define the behavior and characteristics of fluids in various physical and engineering contexts.
