Why do mercury is more viscous than that of water?



Answer for class 6 syllabus​

Answer 1

Explanation:

If the adhesive forces between water molecules and the molecules of the surface are weak compared to the cohesive forces between the water molecules, the water does not “wet” the surface. ... On the other hand, the cohesive forces between mercury atoms are much greater than the adhesive forces between mercury and glass.
