Chapt. 15 Fluids 135 kinetic energy. They have virtually no resistance to shear stresses. The atoms or molecules only touch during collisions and are usually widely separated. Of course, atoms and molecules have no hard edges, but they do have regions of strong interaction and it is these regions that touch. Atoms and molecules resist compression, but they not relatively strongly since they are not touching. If compressed very highly, they usually change to another phase of matter.
