Challenge Problems
Push your limits with challenges.
Question 1
Analyze the impact of increased temperature on the viscosity of a liquid versus a gas. What practical implications can arise from understanding this behavior?
💡 Hint: Consider examples from everyday experiences with cooking oil versus air.
Question 2
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?
💡 Hint: Think about how the mixture behaves under different mixing speeds.
