Fluid Behavior in Liquids and Gases

Fluids include liquids and gases, and they behave differently from solids because of how their molecules are arranged. In solids, molecules are tightly packed and held by strong intermolecular forces. That structure helps solids keep their shape and resist deformation.

Fluids differ from solids mainly in their molecular structure and stress response. Solids have tightly packed molecules with strong intermolecular forces, maintaining their shape and resisting deformation.

In contrast, fluids have molecules that are farther apart with weaker forces, allowing them to flow easily.

A fluid, which incl...
