Question

The main cause of viscosity is (A) Force of repulsion between molecules (B) Cohesive forces (C) adhesive forces (D) both cohesive and adhesive forces

Tardigrade Admin · Accepted Answer

When the inter-molecular forces of attraction are strong within a liquid, there is a viscosity. Cohesive forces are attractive forces exist between molecules of the same substance. So, cohesive forces are the main cause of viscosity. Adhesive forces are attractive force between unlike molecules.

Force of repulsion between molecules

Cohesive forces

adhesive forces

both cohesive and adhesive forces
