👉 A fluid, specifically a liquid, is an exclusively fluid state of matter characterized by the absence of a definite shape and volume. Unlike solids, which maintain a fixed form, or gases, which expand to fill any container, liquids flow and take the shape of their container while retaining a consistent volume. This unique property arises from the weak intermolecular forces between liquid molecules, allowing them to slide past one another without losing cohesion. As a result, liquids are neither compressible nor have a fixed volume, making them distinct from solids and gases in their physical behavior.
