Question

What do you mean by the term “Rheology”?

(a) Study of materials with both solid and fluid characteristics

(b) Study of materials with only solid characteristics

(c) Study of materials with only fluid characteristics

(d) Study of material with both fluid and gas characteristics

I got this question in an interview.

I would like to ask this question from Classification of Fluids in chapter Fluid Flow and Mixing of Bioprocess Engineering

Answer 1

The correct answer is (a) Study of materials with both solid and fluid characteristics

Easy explanation: It is the study of the flow of matter, primarily in a liquid state, but also as “soft solids” or solids under conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force. It is a branch of physics which deals with the deformation and flow of materials, both solids and liquids.
