Question

Which of the following has similar characteristics?

(a) solid and liquid

(b) liquid and gas

(c) solid and gas

(d) cannot be determined

This question was posed to me at a job interview.

My question is taken from Finite Control Volume Approach in chapter Aerodynamics – Fundamental Principles and Equations of Aerodynamics

Answer 1

Right option is (b) liquid and gas

The best I can explain: When force is applied to liquid and gas, there will be an increasing deformation, proportional to the rate of change of deformation. Also, the molecules in liquid and gas are loosely packed. When filled in a container, they take the shape of that container.
