LIQUIDS FLOW
Because liquid particles can move past each other, they can flow. This is very important when transporting liquids from one place to another through pipes or water ways.
VISCOSITY is a measure of the resistance of a liquid to flowing.
The viscosity of a liquid increases as the temperature of a liquid decreases.
This means that the colder the liquid the more difficult it is for the liquid to flow. In the diagram, the chilled red liquid is flowing very slowly. It flow is so slow that the liquid is moving out of the glass like a thick blob of ketchup.
The viscosity of a liquid decreases as the temperature increases.
This means that the warmer the liquid, the faster a liquid can flow.
As the viscosity of a liquid increases, the thicker is the liquid and the more sluggish is it ability to flow.
The colder ocean water is, the more viscous is the water.
