👉 A continuously fluid, often used to describe a substance that flows smoothly and continuously without distinct boundaries, is a material or state of matter that maintains its form while adapting to the shape of its container. Unlike solids, which have a fixed shape and volume, or liquids, which flow but retain some shape, a continuously fluid can change its form while still flowing. Examples include water, air, and certain polymers or biological fluids like blood. This fluidity allows these substances to move easily and take on the contours of their surroundings, making them essential in various natural processes and industrial applications.
