Question 6 • *STPSB_Environmental Science 2627
Stronger attraction between mercury atoms means mercury has stronger cohesive forces. Stronger cohesion generally produces greater surface tension, so mercury is likely to have a higher surface tension than water. Capillary action depends on both cohesion and attraction to the surface of the tube, and mercury’s weak attraction to many surfaces means it does not necessarily show greater capillary action; it is also not very soluble in water.
