Why does mercury not wet glass?? |
|
Answer» Hindi m ans milga kya Mercury does not wet the glass because the cohesive force with the drops is stronger than the adhesive force between the drops and glass. Mercury does not wet glass - the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass. When liquid mercury is confined in a tube, its surface (meniscus) has a convex shape because the cohesive forces in liquid mercury tend to draw it into a drop. |
