Question

The force of attraction between the molecules of the same kind is called

• A. Adhesive force
• B. Attractive force
• C. Cohesive forces
• D. Repelling force

Answer 1

The correct option is C

Cohesive forces

The explanation for the correct option:

(C) Cohesive forces:

• These are the type of forces that exist between similar types of molecules of a substance.
• For example, Attraction between molecules of water.
• A strong force of cohesion results in the formation of water droplets on any surface.

The explanation for the incorrect options:
(A) Adhesive force :

• These are the type of forces that exist between different types of molecules of a substance.
• For example, The attraction between paint and water molecules

(B) Attractive force:

• Attraction is a force between two charges that are different or unlike.
• For example, The force between an anion and a cation.

(D) Repelling force:

• Repulsion is a type of movement between two charges that could be identical or similar.
• For example, The force between two electrons (both having negative charge).

Thus, the correct option is option(C).
