36.1.2.4. Viscosity of fluid

Try these first

1. 1.

   What is viscosity?

   Hint

   Think about how thick or runny a fluid appears.

2. 2.

   How does temperature affect viscosity?

   Hint

   Consider how warm syrup flows compared to cold syrup.

3. 3.

   What does viscosity measure?

   • Thickness of fluid
   • Density of fluid
   • Color of fluid

   Hint

   Think about how syrup compares to water.

4. 4.

   True or False: Higher viscosity allows for easier flow through porous materials.

   • True
   • False

   Hint

   Consider how it feels to pour thick substances.

5. 5.

   If oil is spilled into a river, how would its viscosity affect the clean-up efforts?

   Hint

   Think about how different liquids spread out in water.

6. 6.

   Propose a strategy for modifying a cement mixture to control its viscosity on-site, providing a brief justification for your choice.

   Hint

   Consider the consequences of too thick a mixture.
