Answer 4

What accounts for water's properties of adhesion and cohesion?

Answer 5

Water is a polar molecule because the oxygen atom pulls the electrons in the covalent bonds towards it and away from the hydrogen atoms. So the oxygen is a bit negative and the hydrogen is a bit positive. This means it can pack efficiently round polar molecules. More relevantly, the water molecules can bind together because of these differences in charge meaning they are more coherent than less polar molecules of similar size. I guess water will stick to charged surfaces because of the polar nature too. I'm calling water polar because each bond has a more positive and a more negative end.
