A very small amount of mercury on placing
over a clean glass plate forms a tiny spherical
ball.​

Answer 1

Answer:

Mercury has a much greater force of cohesion than its adhesive force with glass. ... therefore the molecules of mercury rearrange themselves so that no unbalance force acting upon the molecules of mercury.in doing so they take a spherical shape.

please mark me brainlist ☺

Answer 2

• FIRSTLY  MOLECULES OF MERCURY PULL INNER MOLECULE
• INWARDS.
• BUT THEY DON'T MOVE IN AS THERE IS MOVEMENT OPPOSING INWARD MOVING MOLECULES DUE TO THIS TENSION IS CAUSED NEAR THE EDGE.
• IN THIS WAY MOLECULES START TO REARRANGE THEMSELVES AS NO UNBALANCED FORCE SHOULD ACT UPON THEM.
• THIS MAKE A MERCURY TURN INTO SPHERICAL SHAPE.
