Sci 8 Unit A Lesson 8 Viscosity

If a liquid has high viscosity, it probably has:

• strong resistance to flow
• weak resistance to flow

What is viscosity?

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

What is flow rate?

• The speed of a fish swimming across a lake.

• The speed of a rocket going to the moon.

• The speed which a fluid flows from one point to another.

How is viscosity & density affected when a fluid is heated?

• viscosity increases & density increases

• viscosity decreases & density decreases

• viscosity decreases & density increases

• temperature has no affect on viscosity or density

As the viscosity of a liquid increases, the liquid – 

• conducts electricity.
• forms a precipitate.
• pours more slowly.
• evaporates more quickly.
