Detailed explanation-1: -The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. The molecules at the surface do not have other like molecules on all sides of them and consequently they cohere more strongly to those directly associated with them on the surface.

Detailed explanation-2: -“Surface tension is the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimise surface area”.

Detailed explanation-3: -Cohesion: Water is attracted to water, and Adhesion: Water is attracted to other substances. Surface tension in water might be good at performing tricks, such as being able to float a paper clip on its surface, but surface tension performs many more duties that are vitally important to the environment and people.

Detailed explanation-4: -The surface tension of water is about 72 mN/m at room temperature which is one of the highest surface tension for liquid. There is only one liquid having higher surface tension and that’s mercury which is a liquid metal with a surface tension of almost 500 mN/m.

Detailed explanation-5: -Cohesive forces are responsible for surface tension, a phenomenon that results in the tendency of a liquid’s surface to resist rupture when placed under tension or stress.
