Understanding Fluids: Newtonian and Non-Newtonian

What is the primary role of fluids in everyday life?

• To maintain hydration and serve various functions

• To provide nutrients

• To act as a solid base for structures

• To replace air in breathing

Which of the following is a characteristic of Newtonian fluids?

• They are always solid at room temperature

• They evaporate quickly

• They have a constant viscosity regardless of force

• Their viscosity changes with applied force

Which of the following is an example of a Newtonian fluid?

• Water

• Quicksand

• Oobleck

• Ketchup

What happens to the viscosity of dilatant fluids when force is applied?

• It evaporates

• It decreases

• It remains constant

• It increases

Which category of non-Newtonian fluids does ketchup belong to?

• Thixotropic

• Rheopectic

• Pseudoplastic

• Dilatant

What was a major challenge in understanding non-Newtonian fluids in oil extraction?

• The fluids solidified at high temperatures

• The fluids became more viscous when pumped faster

• The fluids became less viscous with increased flow

• The fluids evaporated too quickly

What innovative method did scientists use to study non-Newtonian fluids?

• Using high-speed cameras

• Heating the fluids to high temperatures

• Freezing the fluids

• Creating a custom medium with glass beads

What phenomenon was observed when polymers in non-Newtonian fluids tumbled around?

• Thermal expansion

• Chemical reaction

• Elastic turbulence

• Magnetic alignment

How might the new understanding of non-Newtonian fluids be applied?

• In designing better clothing materials

• In developing new cooking techniques

• In purifying groundwater

• In creating new types of beverages

What is still not fully understood about non-Newtonian fluids?

• Their taste

• Their ability to freeze

• Their elastic turbulence

• Their color changes
