Question

Which model best describes the particles of a solid and their motion?


people seated in an auditorium

beads moving around in a rattle

students walking through a crowded hall

bricks cemented together in a wall

Answer 1

The model that best describes the particles of a solid and their motion is bricks cemented together in a wall. In a solid, particles are closely packed and strongly bonded, similar to bricks being held together by cement in a wall. The particles in a solid vibrate in place, but their overall positions do not change, just like the bricks in a wall do not move independently.
