Quicksand is an example of a __________ fluid?
Correct answer: B. Dilatant
- A. Bingham plastic
- B. Dilatant
- C. Newtonian
- D. Pseudo plastic
Explanation
Quicksand becomes more resistant when disturbed because its apparent viscosity increases with increasing shear rate, which is characteristic of a dilatant fluid. Pseudoplastic fluids show the opposite trend, becoming easier to flow when sheared.
