Water has properties of cohesion and adhesion.
Explanation:
The single Hydrogen atom and double Oxygen atoms attach to each other in such a way their are minute polar polarity differences. Electron bonds will combine to form one side of the compound as being positive and the other side positive. Positive side of other H2O molecules will attach to the negative side.
