Cohesive forces are the intermolecular attractions that hold molecules of the same substance together, playing a crucial role in the physical properties of liquids. They are responsible for phenomena such as surface tension and the formation of droplets, significantly influencing how substances interact at a molecular level.

Surface tension is the cohesive force at the surface of a liquid that allows it to resist external forces, due to the imbalance of intermolecular forces between the liquid's molecules and those in the air. This phenomenon is responsible for the formation of droplets, the ability of small objects to float on a liquid surface, and the capillary action observed in thin tubes.
