← ScienceWhich outcome occurs when a non-Newtonian fluid experiences shear-thinning?
A)Viscosity decreases under applied stress✓
B)Fluid exhibits dilatant characteristics sharply
C)Fluid solidifies due to shear thickening
D)Density increases as shear rate reduces
💡 Explanation
When a shear-thinning fluid is subjected to shear stress, the **viscosity decreases** because intermolecular alignment changes with shear rate exhibiting **thixotropy**; therefore resistance to flow reduces rather than increases, because no additional mechanical work is input.
