Water meniscus in a glass tube is concave while that of mercury is convex. Why ?

Text Solution

AI Generated Solution

To understand why the meniscus of water in a glass tube is concave while that of mercury is convex, we need to consider the concepts of cohesive and adhesive forces. ### Step-by-Step Solution: 1. **Define Cohesive and Adhesive Forces**: - **Cohesive Forces**: These are the intermolecular forces that hold the molecules of the same substance together. In liquids, this leads to surface tension. - **Adhesive Forces**: These are the intermolecular forces that occur between different substances. For example, the forces between water molecules and the molecules of the glass. ...
