Force of attraction between molecules of the same substance is called ______.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. cohesive force.
The force of attraction between molecules of the same substance is called cohesive force or cohesion.
This intermolecular force is responsible for holding the molecules of a substance together. A classic example of cohesive force is a water droplet forming on a surface. The water molecules are more strongly attracted to each other than to the molecules of the surface, causing them to pull together into a rounded shape. This same force gives water its surface tension and allows a liquid to resist being separated. In contrast, the force of attraction between molecules of different substances is known as adhesive force.
