What are the attractive forces that increase surface tension?
-Would it be cohension and adhension? Thanks
You can read about surface tension here.

Is adhesion an attractive force?
Yes, you are correct. The attractive forces that increase surface tension are cohesion and adhesion.
Cohesion refers to the intermolecular forces between molecules of the same substance. In the case of surface tension, cohesion is responsible for the molecules at the surface of a liquid being more strongly attracted to each other than to the molecules in the bulk. This inward pulling force causes the surface of a liquid to behave like a stretched elastic sheet, minimizing the surface area.
Adhesion, on the other hand, refers to the intermolecular forces between molecules of different substances. In the context of surface tension, adhesion helps in attracting the liquid molecules to the surface of another material, such as a solid. This adhesion between the liquid and the solid further contributes to the increase in surface tension.
To determine the attractive forces that increase surface tension, you can examine the intermolecular forces between the molecules of the substance in question. Cohesion and adhesion are the two main forces that play a significant role in surface tension phenomena.
