Why does water form a spherical shape on wax paper, instead of spreading out flat?

a surface tension attracts water molecules inward.

b surface tension makes water molecules sticky.

c heat capacity makes water molecules absorb energy.

d heat capacity makes water molecules release energy.

Answer;

A Surface tension attracts water molecules inward.

Explanation;

-Due to surface tension the water molecules are pulled towards one side due to the surface hence a spherical sale is formed.

-Surface tension is responsible for the shape of liquid droplets. Although easily deformed, droplets of water tend to be pulled into a spherical shape by the cohesive forces of the surface layer. In the absence of other forces, including gravity, drops of virtually all liquids would be approximately spherical.
