Answer 2

Capillary Action and Mercury

Capillary action is the phenomenon where a liquid rises or falls in a narrow tube, such as a capillary tube. The behavior of liquids in capillary tubes is influenced by several factors, including the cohesive forces between the liquid molecules and the adhesive forces between the liquid and the tube's material.

Water is known to exhibit capillary action, where it rises in a capillary tube. This is because the cohesive forces between water molecules are stronger than the adhesive forces between water and the tube's material. As a result, the water molecules are more strongly attracted to each other, causing them to climb up the tube against the force of gravity.

On the other hand, mercury does not exhibit capillary action and tends to fall in a capillary tube. This is because the cohesive forces between mercury molecules are weaker than the adhesive forces between mercury and the tube's material. As a result, the adhesive forces pull the mercury down, causing it to descend in the tube.

In the case of water, the adhesive forces between water and the tube's material are stronger than the cohesive forces between water molecules, allowing water to climb up the tube. In the case of mercury, the cohesive forces between mercury molecules are stronger than the adhesive forces between mercury and the tube's material, causing mercury to descend in the tube.

To summarize: - Water rises in a capillary tube due to stronger adhesive forces between water and the tube's material compared to the cohesive forces between water molecules. - Mercury falls in a capillary tube due to stronger cohesive forces between mercury molecules compared to the adhesive forces between mercury and the tube's material.
