Respuesta :
The adhesion forces between mercury and glass are far weaker than the cohesive forces between mercury atoms causing the meniscus in the capillary tube to be lower than the meniscus in the beaker.
What is surface tension?
The force operating at a border between two phases is measured as surface tension.
Surface tension at liquid-air interfaces is caused by the higher attraction of liquid molecules to each other than air molecules.
Due to the relatively strong attraction of water. Hence molecules of water have high surface tension.
Because the water wets the glass and seeps up the tube's side when it is contained in a glass tube, the meniscus of the water has a concave form.
The cohesive forces between mercury atoms, on the other hand, are far stronger than the adhesion forces between mercury and glass.
The meniscus in the capillary tube is, therefore, higher than the meniscus in the beaker, but with mercury, the meniscus in the capillary tube is lower than the meniscus in the beaker.
Hence, the meniscus in the capillary tube is lower than the meniscus in the beaker
