|
|
tension
|
|
|
adhesion
|
|
|
cohesion
|
|
|
gravity

Explanation:
Detailed explanation-1: -Hydrogen bonds are attractions of electrostatic force caused by the difference in charge between slightly positive hydrogen ions and other, slightly negative ions.
Detailed explanation-2: -More precisely, the positive and negative charges of the hydrogen and oxygen atoms that make up water molecules makes them attracted to each other.
Detailed explanation-3: -A cohesive force holds water molecules together. This force is an intermolecular hydrogen bond, which is a weak or temporary sort of chemical connection. It is formed when one HOH’s hydrogen reacts with the hydrogen of another HOH. As a result, as they cohere, they create a water drop.
