What is produced on the top of a pool of water by the mutual attraction between water molecules?
-surfactant
-surface tension
-a much smaller volume
-a much higher density

surface tension

Explanation:

Surface tension is the net downward force acting on the surface of liquids due to the cohesive nature of liquids.

Water molecules are bonded by strong hydrogen bonding between the hydrogen atom and the electronegative oxygen atom. Thus water molecules present on the surface are strongly attracted by the molecules present below the surface and thus act as a stretched membrane.

The surface acquires a minimum surface are and thus acquire a spherical shape.

i have no clue hope you find the answer
