And we know that our electric force is directly or inversely proportional to the square of the distance between our two charges. And so because the distance here will be so small. If the distance is small, the force will become large. And if the force is large, this interaction is very strong. And this type of interaction between the H atom of one water molecule and the oxygen atom of another water molecule is known as a hydrogen bond. So, once again, water molecules interact strongly with other water molecules via electrical forces or, to be more specific, electromagnetic forces.
