It is called surface tension. Somehow the water molecules are "magnetic" to each other. Hydrogen bonds are the primary intermolecular forces responsible for the unusually high cohesion forces (this is the cause behind surface tension) of water. The H-O bonds in the water molecules are highly polarized because of the large electronegativity differences between oxygen and hydrogen and there is a partial negative charge on the oxygen and a partial positive charge on the hydrogen. These partial charges are still able to attract each other and these electric attractions give rise to the high cohesion of water. Other compounds that exhibit this phenomenon of hydrogen bonding include ethanol and ammonia. Biological macromolecules also use hydrogen bonds to maintain their strucutres. For example, the two strands of DNA are held together by hydrogen bonds.
This phenomenon is called cohesion. A water molecule can form four hydrogen bonds; the structure is stable and the intermolecular forces are important, explaining the cohesion of water molecules.
no
The property is cohesion. Cohesion among water molecules at the water's surface produces surface tension.
no, i don't think they are!:)
hydrogen bonds
They type of chemical bond that is responsible for the properties of adhesion and cohesion is hydrogen bonding. In cohesion the water's hydrogen bonds make water self-sticky, it beads up. In adhesion water has the ability to climb up the wall of any container it is in.
Hydrogen bonds are the reason for cohesion and Van Der Waals equation is the cause of adhesion.

Cohesion of water molecules occurs through the formation of hydrogen bonds between molecules

no
no
allows water molecules to stick together creating cohesion
