CHAPTER 6 SECTION 3 REVIEW Matter and Heat

1. What is a solid? A. Particles move fast enough to overcome some of the attraction between them, and so they can slide past one another. B. Particles move fast enough to overcome most of the attraction between them, and so they move independently of one another. C. Particles do not overcome the attraction between them, and so they vibrate in place. D. Particles move so slowly you can see them.

ANSWER: In a solid… C. Particles do not overcome the attraction between them, and so they vibrate in place.
