Detailed explanation-1: -The cohesion of water creates surface tension where air and water meet.
Detailed explanation-2: -Cohesion makes a water drop a drop For water, this state happens when a water molecule is surrounded on all sides by other water molecules, which creates a sphere or ball (perfectly round if it was in outer space).
Detailed explanation-3: -Have you ever filled a glass of water to the very top and then slowly added a few more drops? Before it overflows, the water forms a dome-like shape above the rim of the glass. This dome-like shape forms due to the water molecules’ cohesive properties, or their tendency to stick to one another.
Detailed explanation-4: -As explained, the cohesive force between the molecules causes surface tension. The stronger the cohesive force, the stronger the surface tension. The water molecule has two hydrogen atoms bond to an oxygen atom through covalent bonding.
