Viscosity is the resistance of a liquid to flow. The greater a liquid's viscosity, the more slowly it flows. (The viscosity of a liquid is related to how easily it's molecules flow past one another. It depends on the attractive forces between molecules and such that they tend to become entangled.)
28 sie 2022 · Viscosity is the result of frictional interactions within a given liquid and is commonly expressed in two different ways. Dynamic Viscosity. The first is dynamic viscosity, also known as absolute viscosity, which measures a fluid’s resistance to flow.
26 cze 2023 · The viscosity of a liquid always decreases as temperature increases. As the molecules acquire more energy, they can escape from their mutual traction more readily. Long-chain molecules can also wriggle around more freely at a higher temperature and hence disentangle more quickly.
30 sty 2023 · Viscosity can be not only a fluid’s resistance to flow but also a gas’ resistance to flow, change shape or movement. The opposite of viscosity is fluidity which measures the ease of flow while liquids such as motor oil or honey which are “sluggish” and high in viscosity are known as viscous.
As temperature increases what happens to viscosity of a liquid? As heat is added to a fluid, its particles speed up and spread out (the attractive forces between the particles decrease) so it gets easier for them to move past each other.
