3 describing describe how the motion and arrangement of particles in a substance change as the substance freezes.

Explanation:

When a substance freezes, it changes from a liquid to a solid state. In the liquid state, particles are in constant motion, sliding past each other. As the substance freezes, the temperature decreases. The particles lose kinetic energy. Their motion slows down. Eventually, they arrange themselves in a more orderly, fixed pattern characteristic of a solid. In a solid, particles vibrate in fixed positions.

Answer:

As a substance freezes, the particles' motion slows (lose kinetic energy) and they arrange more orderly (fixed pattern as in a solid, vibrating in place instead of sliding like in a liquid).
