cohesion

Cohesion is the force that holds molecules of a liquid together. It is the reason why water droplets form spheres and why raindrops stay together as they fall through the air.

Cohesion is caused by the attraction of the molecules' positive and negative charges. The molecules of a liquid are constantly moving, and they are constantly bumping into each other. When two molecules bump into each other, their positive and negative charges attract each other. This attraction helps to hold the molecules together.

Cohesion is a very important property of liquids. It is what allows liquids to form droplets and to stay together as they fall through the air. Cohesion also helps to prevent liquids from evaporating too quickly.

Imagine that you are a group of people. You are all holding hands, and you are all trying to stay together. You are like the molecules of a liquid. The force that is holding you together is like cohesion. In the same way, the molecules of a liquid are held together by the force of cohesion. This force helps to keep the molecules together and prevents them from spreading out.

The cohesive properties of the material made it difficult to break.
