It depends on the substance and the physical state of the substance.
molecules are arranged in good order along the fibers
In a fluid manner
relating to or denoting a state of a liquid crystal in which the molecules are oriented in parallel but not arranged in well-defined planes. Compare with smectic . noun a nematic substance. ORIGIN early 20th cent.: from Greek nēma, nēmat- ‘thread’ + -ic .
The diagram of molecules shows how atoms are arranged in a molecule. In chemical reactions, molecules interact and rearrange their atoms to form new substances. The diagram helps us understand how molecules change during a chemical reaction.
DNA molecules are arranged by genetics
Crystalline means that the molecules are arranged in a specific pattern. Amorphous means that the molecules are arranged randomly.
In a gas, molecules are arranged randomly and move freely in all directions. They have high kinetic energy and collisions between molecules are elastic. The distance between molecules is large compared to the size of the molecules themselves.
In a fluid manner
Polar molecules are attracted to other polar molecules with an opposite charge.
Adhesive forces are the attraction between molecules of different substances. This differs from cohesive forces which is attraction between same substances.
randomly
DNA molecules are arranged as a tightly coiled helix. (:
