👉 The term "all fluid" refers to a substance that can take the shape of its container and flows easily, like water or oil. It encompasses all materials that are primarily composed of molecules held together by intermolecular forces, allowing them to move and rearrange without breaking apart. This characteristic of fluidity is crucial in various natural processes, from the movement of blood in our circulatory system to the flow of air through our lungs. In essence, "all fluid" describes any material that exhibits liquid-like behavior under normal conditions, adapting its form to fill any space it occupies.
