Question

Josh and his friends were asked to do a skit to show the motion of the particles in a solid. Which of the following skits best shows this motion?

A. They stood back to back in pairs.
B. They stood at arms' length moving in a circle.
C. They stood in a tight group without moving.
D. They stood in a tight group swaying back and forth.

Answer 1

Josh and his friends should perform a skit where they stand in a tight group swaying back and forth, as this demonstrates the vibrational motion of particles in a solid.

Step-by-step explanation:

The question asks which skit best shows the motion of particles in a solid. According to kinetic molecular theory, particles in a solid are tightly packed together and vibrate in place due to intermolecular attraction. They do not move freely about but are restricted to vibrating around their fixed positions.

Therefore, the skit that best depicts this behavior would be the one in which Josh and his friends stand in a tight group swaying back and forth, representing the vibrational movement of the particles within a solid structure.
