fluids

Fluids are substances that can flow and take the shape of their container. They include liquids and gases. In a liquid, particles are close together but can slide past each other, allowing the liquid to move smoothly. Gases have particles far apart and are compressible, meaning they can be squished into smaller spaces. Fluids are essential in nature and technology, enabling processes like blood circulation, air movement, and the operation of hydraulic systems. Their ability to flow and adapt to their containers makes them unique and vital in many aspects of life and engineering.
