Meniscus in mercury (left) and water compared. Mercury shows a convex meniscus (the centre is higher than the edges),because internal cohesive forces are stronger than the force between the glass wall and the metal. In contrast,water exhibits a concave meniscus,because the attraction between the wall and the water is stronger than the water's internal cohesion | |
