Which of the following best describes what causes water molecules to exhibit properties such as cohesive and adhesive behavior?

water molecules are polar, having partially positive and partially negative ends.
water molecules have both a hydrophobic end and a hydrophilic end.
water molecules are capable of dissolving both polar and nonpolar substances.
water molecules have a high molecular weight, making them very dense.

Water molecules are polar, having partially positive and partially negative ends.

Explanation:

The water molecules are polar which allows them to react and dissolve various molecules of other substance in them. The water molecule shows the cohesive and adhesive relationship because of this polarity. The water molecules attract the other water molecules by cohesive forces facilitated by the hydrogen bonding. The water molecules when attract the molecules of the other substances by the adhesive forces facilitated by the hydrogen bonding.
