zähflüssigkeit
Zähflüssigkeit refers to the property of a fluid to resist flow. It is also commonly known as viscosity. This resistance arises from the internal friction between the fluid's molecules. When a fluid is subjected to a shearing force, the molecules tend to resist this relative motion, creating a drag. Liquids typically exhibit higher zähflüssigkeit than gases because their molecules are closer together and interact more strongly. Temperature plays a significant role; for most liquids, zähflüssigkeit decreases as temperature increases, as the increased kinetic energy of molecules overcomes intermolecular forces. Conversely, for gases, zähflüssigkeit generally increases with temperature due to more frequent molecular collisions.
Zähflüssigkeit is a crucial property in many scientific and engineering applications. For instance, the lubrication of
