Statement I : Capillary action is due to surface tension.Statement II ...
**Statement I : Capillary action is due to surface tension.**
Capillary action is the phenomenon where a liquid rises in a narrow tube or is drawn into a narrow space against the force of gravity. It occurs due to the combined effects of adhesive and cohesive forces.
**Statement II : Mercury, with its strong cohesive forces and weaker adhesive forces, does not show capillary rise.**
Mercury is a liquid metal with strong cohesive forces, meaning that its molecules have a strong attraction to each other. However, its adhesive forces, or the attraction between the molecules of mercury and the molecules of the container, are relatively weak. As a result, mercury does not show capillary rise in a narrow tube or space.
**Explanation:**
When a capillary tube is immersed in a liquid, the liquid rises or falls in the tube due to the balance between adhesive and cohesive forces. Adhesive forces are the attractive forces between the liquid molecules and the molecules of the container, while cohesive forces are the attractive forces between the liquid molecules themselves.
In the case of capillary rise, if the adhesive forces are greater than the cohesive forces, the liquid will rise in the tube. This is because the liquid molecules are more attracted to the molecules of the container than to each other, leading to a net upward force. The rise of the liquid is governed by the surface tension of the liquid, which is the force that holds the liquid molecules together at the surface.
Mercury, on the other hand, has strong cohesive forces due to its metallic nature. The cohesive forces between mercury molecules are much stronger than the adhesive forces between mercury and the container. As a result, the cohesive forces dominate and prevent capillary rise of mercury in a narrow tube. The surface tension of mercury is not sufficient to overcome the strong cohesive forces and allow it to rise in the tube.
Therefore, both Statement I and Statement II are correct. Statement II provides the correct explanation for why mercury does not show capillary rise.
