What is the term for liquids that exhibit increased resistance and become thicker when the deformation rate rises?
Explanation
Thixotropic fluids decrease in viscosity over time under constant shear, pseudoplastic (shear-thinning) fluids become less viscous as shear rate increases, dilatant fluids (shear-thickening) increase in viscosity with higher shear rates, and Newtonian fluids maintain constant viscosity regardless of shear rate.
