👉 Molecular fluids, or liquids, are unique states of matter where molecules are close enough to interact with one another but not so tightly bound that they form a solid structure. At the molecular level, these fluids exhibit properties such as viscosity, allowing them to flow and change shape while maintaining a constant volume. The interactions between molecules in a liquid are primarily governed by weaker forces like van der Waals forces and hydrogen bonding, which enable the molecules to slide past each other. This results in a fluid that can adapt its shape to fill any container, yet retains its liquid form. Unlike solids, where molecules are fixed in a rigid lattice, in molecular fluids, the movement of molecules is dynamic and continuous, making them essential for processes like heat transfer, diffusion, and the behavior of everyday substances like water and oils.
