👉 Fluids, encompassing water and other substances like oils and gases, exhibit diverse behaviors due to their unique molecular structure. These substances flow and change shape without breaking apart into simpler components, a property known as fluidity. Molecular interactions, such as hydrogen bonding in water, create cohesive forces that allow fluids to resist external forces and flow smoothly. This fluidity is crucial for various natural processes, including heat transfer, nutrient transport in living organisms, and the movement of tectonic plates. The viscosity, or resistance to flow, of fluids varies greatly depending on factors like temperature and pressure, influencing their behavior in different environments.
