Fluidity

Fluidity refers to the ability of a substance to flow and change shape smoothly without breaking apart. It's a property seen in liquids and gases, allowing them to adapt to the container they're in. For example, water can spread out and fill a glass, while air moves effortlessly around obstacles. Fluidity depends on factors like temperature and pressure—higher temperatures usually increase it. Understanding fluidity helps in fields like engineering, physics, and everyday life, where controlling or predicting how substances move is important for processes such as transportation, manufacturing, and natural phenomena.
