Answer 2

Answer:

Plastic fluid is a viscoplastic material that, at low stresses, behaves as a rigid body but flows as a viscous fluid at high stresses. It is a common mathematical model of mudflow used in drilling engineering and slurry handling.

Explanation:

Non-Newtonian liquids include polymer solutions, dispersions, and melts. This means that their apparent viscosity varies with shear rate and increases rapidly as molecular weight increases (number of repeat units).

As a result, the viscosity of a polymer melt is always greater than the viscosity of the corresponding monomer. This is due to polymer molecule entanglement and intermolecular forces.

The formation of a silica network structure as a result of attractive particle-particle interactions due to hydrogen bonding between silanol groups can explain the solid-like behavior at low shear stress.

Thus, the fluid that shows plastic flow behavior is paint.

The correct option is (c) paints.
