👉 The basically fluid, often referred to as a liquid or a non-Newtonian fluid, is a substance that exhibits properties of both liquids and gases, but not strictly one or the other. Unlike typical liquids, which maintain a constant shape and volume, and gases, which expand to fill any container, fluids like oils, honey, or even certain biological fluids can change their viscosity (thickness) based on the applied force or shear rate. For example, when you stir honey, it flows more easily, becoming less viscous, but if you apply more force or shake vigorously, it thickens. This behavior is due to the interactions between the fluid's molecules and their ability to rearrange under stress, making them fundamentally different from simple liquids or gases.
