fluidität
Fluidität, often translated as fluidity, refers to the quality or state of flowing easily and smoothly. In physics, it is a property of matter, typically observed in liquids and gases, that allows them to change shape to conform to their container. This characteristic is a direct consequence of the weak intermolecular forces present in these states, enabling particles to move past one another with relative freedom. The absence of a fixed shape and volume, or the ability to adapt to them, is central to the concept of fluidität.
The term fluidität can also be applied metaphorically to describe adaptability, flexibility, and the smooth transition
