What happens to the viscosity of Newtonian liquids when the temperature is increased?
Their viscosity decreases
What causes the viscosity of Newtonian liquids to decrease?
Increasing the temperature
What happens to the viscosity of Newtonian gases when the temperature is increased?
Their viscosity increases
What is viscosity a measure of?
Resistance to movement
What causes the viscosity of a Newtonian gas to increase?
Increasing the temperature
What causes the viscosity of a Newtonian gas to decrease?
Decreasing the temperature
What causes the viscosity of a Newtonian liquid to increase?
Decreasing the temperature
What are the two types of Non-Newtonian fluids?
Shear-thickening and shear-thinning
What are type of fluids are shear-thickening and shear-thinning fluids?
Non-Newtonian
What causes the viscosity of a shear-thickening fluid to increase?
Applying a shear force (shaking, stirring, compressing) to the fluid
What happens to a shear-thickening fluid when a shear force is applied to it?
The viscosity of the fluid increases
What causes the viscosity of a shear-thinning fluid to decrease?
Applying a shear force (shaking, stirring, compressing) to the fluid
