How do the cohesive forces of water affect folded paper?

Cohesion is a force where both like molecules undergoes intermolecular attraction with each other within a body which acts to unite them., and this would cause surface tension amongst the two bodies. It is a force that binds the water and solidified particles together in a group strongly together.


See, if you put a paper clip on a water, why won't it sink? Simple, the cohesive forces of the particles near the water's surface acted on the papar clip, so the net force of the paper clip and the water surface cancel out, so the paper clip float.


So, in the case of water and folded paper, they are both in different states, one liquid and the other solid state, so cohesive forces would be present between the water and paper.
