What do water's properties of cohesion, surface tension, and adhesion have in common? 1) all have to do with the ionic bonds between water's atoms. 2) all result from the bonding within the hydrogen atom. 3) all are caused by the low electronegativity of the oxygen atom. 4) all are properties related to the attraction between water molecules.
