On a clean glass plate a drop of water spreads to form a thin layer whereas a drop of mercury remains almost spherical because:

cohesion of water is greater than its adhesion with glass.

density of mercury is greater than that of water.

cohesion of mercury is greater than its adhesion with glass.
