WebMay 24, 2013 · Meniscus is caused by surface tension. Water is strongly attracted to glass and its meniscus is concave (adhesion). Mercury is more strongly attracted to itself (cohesion) and is convex in meniscus. WebCohesion While we have alluded to the way water adheres to glass and forms a concave meniscus, we have not discussed why water rises up the tube to form an elevated column above the level of the supply vessel. This forces us to …
WebCompetition between the forces of adhesion and cohesion are important in the macroscopic behavior of liquids. ... The curved surface of a fluid in a tube is called a meniscus. The tendency of surface tension is always to reduce the surface area. Surface tension thus flattens the curved liquid surface in a capillary tube. This results in a ... WebCohesion: Cohesion is the attractive force between "like" molecules. Many properties of water such as surface tension occur because of cohesive forces between water molecules.
