Answer 1

here's the answer to your question

Describe molecularity of surface tension?

• Surface tension has been well- explained by the molecular theory of matter. According to this theory, cohesive forces among liquid molecules are responsible for the phenomenon of surface tension. The molecules well inside the liquid are attracted equally in all directions by the other molecules.
• Surface tension is a fundamental property of the surface of liquid. Surface tension is responsible for the curvature of the surfaces of air and liquids. Surface tension is responsible for the ability of some solid objects to “float” on the surface of a liquid.

Answer 2

Surface tension has been well-explained by the molecular  theory of matter. According to this theory, cohesive forces among liquid molecules are responsible for the phenomenon of surface tension.

Explanation:

• Surface tension could be defined as the property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of the water molecules.
• The molecules well inside the liquid are attracted equally in all directions by the other molecules.
• The surface tension is the physical property experienced by a liquid due to the free or unbounded molecules along the boundaries of the liquid container.
• It is defined as the force exerted by the liquid molecules along the upper surface of a container per unit length of the container.
• As temperature decreases, surface tension increases. conversely, as surface tension decreases strong; as molecules become more active with an increase in temperature becoming zero at its boiling point and vanishing at critical temperature.
