4 cards from this section. Quick, good the night before a test.
What is shear stress?
Think about forces acting in the same direction as the area.
What does viscosity measure?
Consider what happens to a syrup's flow compared to water.
What is shear stress?
Look for definitions related to surface forces.
True or False: Viscosity changes with temperature only in gases.
Consider how liquids behave when heated.
Analyze the impact of increased temperature on the viscosity of a liquid versus a gas. What practical implications can arise from understanding this behavior?
Consider examples from everyday experiences with cooking oil versus air.
Given the definition of Newtonian and non-Newtonian fluids, propose an experiment to measure the viscosity of a non-Newtonian fluid, such as cornstarch and water mixture. What observations would you expect?
Think about how the mixture behaves under different mixing speeds.
