The answer is cohesion.
----------------------
Cohesion is true but there is a more fundamental answer. There are four fundamental forces from which all other forces can be derived: electromagnetic (EM) force, weak force, strong force and gravitational force. Gravitational force is something we can all relate to, i.e. it's what keeps on the ground but surprisingly it's the weakest of all the forces. EM force defines how charged particles interact and the strong force and weak force are short range forces that play vital roles at the nuclear level. That said, all these forces play a key role in holding molecules together but on a microscopic scale strong and weak forces are insignificant because of their limited range. The gravitational attraction is also negligible because molecules have relatively small masses. That leaves the EM force. All molecules carry some sort of charge. While some molecules can have net zero charge, there will still be some polarity. As a result, the electromagnetic force is the main 'glue' that holds molecules together.
Cohesion
If Coulomb's force is gone , the material structure of the Cosmos would be gone. Coulomb's force hold atoms together and molecules together and matter together.
Chemical Bonds
When a material is placed in compression, it undergoes a decrease in volume and an increase in density. The material experiences internal forces that push its molecules or particles closer together, leading to a reduction in its dimensions along the direction of the applied force. At a certain point, the material may deform or fail if the compressive forces exceed its strength.
The force of attraction between molecules below the surface of a liquid is called cohesive force. This force creates an inward pull, causing the liquid molecules to stick together and form a well-defined surface.
Cohesion
If Coulomb's force is gone , the material structure of the Cosmos would be gone. Coulomb's force hold atoms together and molecules together and matter together.
The force that occurs when molecules of an object are pushed together is called compression force. This force causes the molecules to move closer to each other, resulting in a decrease in the object's volume.
The technical name for the force which holds glue to its bonding material is adhesion. Adhesion is the attraction between molecules of different substances, causing them to stick together.
The elastic force you are referring to is compression. Compression occurs when external forces push or squeeze matter together, causing the molecules to move closer to each other and creating pressure within the material. This force is often applied in situations like compressing springs or squishing a soft material.
Sand squeezed together, and aged, can make a pearl.
Chemical Bonds
Compression.
The force that keeps molecules in a fluid together is a combination of weak electromagnetic and strong nuclear forces.
hydrogen bonds,etc.
No, dipole-dipole forces are intermolecular forces - they occur between different molecules. Intramolecular forces, on the other hand, act within a single molecule to hold its atoms together.
