What is viscosity?

• A liquid's resistance to flow.
• a liquids flow.
• a liquid
• gas to solid.

As the temperature increases the viscosity _______________, the molecules move further apart making the liquid "thinner".

• increases

• stays the same

• decreases

Fluids with very high viscosity flow very _______________________.

• fast

• not at all

• slow

• whenever it wants

Fluids with very low viscosity flow very _______________________.

• fast

• not at all

• slow

• whenever it wants

Put the liquids in order from most dense to least dense?

• 4, 3, 2, 1
• 1, 2, 3, 4
