Question

Which of the following models best describes a solid on the microscale? A. Vibrating particles in contact with each other B. Moving particles in contact with each other C. Moving particles with large spaces between particles D. Motionless particles in contact with each other E. Motionless particles with large spaces between particles

Answer 1

answer : B. Moving particles in contact with each other

explanation:

the closest depiction is particles in close proximity but moving around and past each other.

All liquids do have a sort of structure, though. It is generally a short distance thing and for short time periods. The liquids at any given time tend to have zones of organization that are similar to the crystal structure of the solid, but fail to have the strength to hold particles in those structures, so the structures are always changing pieces and are never really fully formed. They tend to fall apart as you move away from a given particle, to lose the organized structure that a solid has. nevertheless, adjacent molecules do tend to place themselves in about the place they would find themselves in the solid, because there is an energy benefit to that sort of organization. The particles are just too energetic to stay there for very long at all and never really fixate at those spots
