Answer 1

Answer:

Explanation:

A

Answer 2

At equilibrium, the thixotropic behavior of a pseudoplastic system exhibit the state of Option (a) gel.

Explanation

• Thixotropy is a shear-thinning property that changes with time. Shaken, agitated, or sheared gels or fluids will gradually become thinner and less viscous over time.
• They take a fixed amount of time to return to a thicker state. Some pseudoplastic fluids show a time-dependent change in viscosity; the longer the fluid undergoes shear stress, the lower its viscosity.

In depth knowledge:

• A thixotropic fluid is a fluid that takes a finite time to achieve an equilibrium viscosity when introduced into a sharp change in the shear rate Some thixotropic fluids rejoin water to form a sol almost instantly, such as ketchup, and are called pseudoplastic fluids. Others, such as yogurt, can take a long time to set and can become nearly solid.
• Many gels and colloids are thixotropic materials that show a stable shape at rest but become fluid when agitated.
