Which statement best explains the reason that the metal part of this seat belt is a better thermal conductor than the plastic part? A. The metal has densely packed particles, which allows for more collisions in a given area. B. The metal has loosely packed particles, which limits energy transfer by the collision of particles. O C. The metal has loosely packed particles, which allows for more collisions in a given area. D. The metal has densely packed particles, which limits energy transfer by the collision of particles.

A. The metal has densely packed particles, which allows for more collisions in a given area.

Explanation:

Different objects exists in different states, which can only be either of the three viz: solid, liquid, and gases. In this question, both the metal part and plastic part of the seat belt are solids. However, one is a metal and the other a plastic.

The particles of solid substances are closely or densely packed together in such a way that increase in temperature or application of heat causes a rapid collision of its particles.

However, in the metal part of the seat belt, the metal has densely packed particles, which allows for more collisions in a given area than the plastic part. This accounts for the reason that the metal part of this seat belt is a better thermal conductor than the plastic part.
