👉 The "explains fluid" refers to a substance, typically a liquid, that has unique properties allowing it to flow and change shape without breaking into distinct pieces when subjected to stress or force. Unlike solids, which maintain a fixed shape and volume, and gases, which expand to fill any container, fluids can move and adapt to their surroundings. This fluidity is due to the cohesive forces between molecules and the lack of a rigid structure, enabling them to flow and take the shape of their container. Examples include water, oil, and air, which can flow, mix, and change volume under various conditions.
