Question

Explain how viscosity is related to the flow and attraction between atoms in a liquid

Answer 1

Viscosity is the resistance of a liquid towards the flow of motion.

Viscosity is also known as fluid friction is the contact force that exists between the atoms. The atoms of liquid upon contact experience a strong force of attraction. Due to this attraction, the atoms of liquid resist the flow of motion.

As a result, either they tend to stick to their place or move very slightly. The higher the resistance is shown by a liquid, the higher will be its viscosity.
