Explanation:

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.

In liquids, the viscosity is due to the cohesive force between its atoms, it is a property characterized by the resistance to flow that is generated from collisions between the molecules.

What is viscosity?

It is the resistance that certain substances have to flow due to shear stresses or tensile stresses.

Characteristics of viscosity

  • All fluids have viscosity due to the collisions between their particles, which move at different speeds.

  • Said particles generate frictional resistance, preventing displacement.

  • A fluid with a very high viscosity will be very close to being a solid, since its particles attract each other with such a force that they prevent the movement of the upper layers.

Therefore, we can conclude that viscosity refers to the resistance that some liquids have during their flow and deformation.
