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 mercury is greater than its adhesion with glass
The reason mercury forms spherical drops while water forms a thin layer is that the cohesion (molecules sticking together) of mercury is greater than its adhesion (molecules sticking to the surface) with glass. Therefore, the correct answer is "Cohesion of mercury is greater than its adhesion with glass."
