If a liquid presents a contact angle of wettability greater than 90°,the material is said to be:

Question

Quizplus · Accepted Answer

A contact angle of wettability greater than 90° indicates that the liquid is not easily wetting the material, and therefore, the material is hydrophobic, meaning it has a low affinity for water. Thixotropic refers to a physical property of certain fluids that exhibit a decrease in viscosity over time when subjected to shear stress, while viscous refers to a thick, sticky consistency of a fluid. Hydrophilic refers to a material that has a high affinity for water and easily wets when in contact with water, which is the opposite of the situation given in the question. Hence, the best choice is C.
