Cohesion or cohesive attraction or cohesive force is the action or property of like molecules sticking together, being mutually attractive.
Similarly, the term “adhesive forces” refers to the attractive forces between unlike molecules, such as mechanical forces (sticking together) and electrostatic forces (attraction due to opposing charges).
In case of a liquid wetting agent, adhesion causes the liquid to cling to the surface on which it rests.

Viscosity

Viscosity is the characteristic of a fluid to exert a force between it so as to reduce the relative motion between the membranes.

Viscous force is the frictional force acting parallel to the membranes in such a way as to interfere with their relative motion between the moving fluid membranes.
