Mercury does not wet glass. This is due to property of liquid known as...
Explanation:
Cohesion is the property of a liquid that causes its molecules to be attracted to each other. It is the force of attraction between molecules of the same substance. In the case of mercury, its cohesive force is greater than its adhesive force. This means that the molecules of mercury are more attracted to each other than they are to the molecules of the glass.
When a liquid wets a surface, it means that the adhesive force between the liquid molecules and the surface molecules is greater than the cohesive force between the liquid molecules themselves. In the case of mercury and glass, the cohesive force between the mercury molecules is too strong, and so it does not spread out over the surface of the glass.
In other words, mercury does not wet glass because the cohesive forces between the mercury molecules are stronger than the adhesive forces between the mercury and glass molecules.
Key Points:
- Mercury does not wet glass
- Cohesion is the force of attraction between molecules of the same substance
- The cohesive force of mercury is greater than its adhesive force to glass
- When a liquid wets a surface, the adhesive force is greater than the cohesive force
- Mercury does not wet glass due to its strong cohesive force

Because cohesive force with in the drops is greater than the adhesive force between glass and the mercury drops. But coming to water cohesive force is less compared to adhesive force so the surface of glass becomes wet
