What is Viscosity?
Viscosity is a measure of how thick or thin a liquid is.
It tells us how easily a liquid can flow.
High Viscosity:
Liquids like honey are thick.
They flow slowly.
Example: Honey is hard to pour quickly.
Low Viscosity:
Liquids like water are thin.
They flow easily.
Example: Water pours out quickly.
How Temperature Affects Viscosity:
Heating a Liquid: Makes it flow more easily (lowers viscosity).
Cooling a Liquid: Makes it flow less easily (raises viscosity).
Example: When honey is warmed, it flows better!
In Summary:
Viscosity helps us understand how liquids behave.
Thick liquids (high viscosity) flow slowly.
Thin liquids (low viscosity) flow quickly.
