Force of attraction between molecules of the same substance is called cohesive force. The force of cohesion is the attraction between molecules of the same type. The force of adhesion is the attraction between various types of molecules. The growth and strength of green granules depend on the cohesive force of tiny particles.

Force of attraction between molecules

While the latter directly impacts the permeability of a packed granule bed, the former influences the size distribution of the final granules generated. All nearby atoms share the cohesive forces that hold molecules together as they descend into a liquid.

Viscosity:

The resistance of a fluid (liquid or gas) to a change in shape or motion of adjacent sections relative to one another is known as viscosity. Viscosity is a metric for a fluid's flow resistance. The poiseuille is the SI unit for viscosity (PI). Newton-second per square metre (N s m-2) and pascal-second are some of its other units (Pa s.). Viscosity's dimensional formula is (ML-1T-1).

Surface tension:

Fluid surfaces have a tendency to contract into the smallest surface area feasible due to surface tension. In order to break a film with a length of 1 cm, surface tension is commonly measured in dynes/cm.

Adhesive force:

One of the effects of electrostatic forces, which are applied to various substances, might be adhesion forces. The force of attraction between water molecules and the walls of xylem vessels is typically referred to as adhesion.

Summary:

Force of attraction between molecules of the same substance is called_____. (a) Viscosity (b) Surface tension (c) Adhesive force (d) cohesive force

Cohesive force is the term for the force of attraction between molecules of the same substance. The attraction between molecules of the same type is the force of cohesion.
