Q. The attractive force between different molecules?
Solution:
- 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.
