Praxis II: Chemistry Exam Prep

Category - General Chemistry

The constituent particles in a substance in its solid state tend to:
  1. Remain motionless.
  2. Vibrate about fixed positions.
  3. Slide freely past one another.
  4. Move constantly in straight lines.
Explanation
Correct Response: B. Vibration occurs in the solid state, and molecules in solids, such as crystal lattices, vibrate about fixed positions. A is incorrect; it is a common misconception that particles do not vibrate in the solid state. Particles in the solid state will vibrate less as temperatures of absolute zero are approached. C is incorrect because movement of particles in the solid state is restricted as a result of interactions with other particles (for example, NaCl in a crystal lattice). D is incorrect because particles in the solid state vibrate in such a way that interactions with neighboring particles are maintained.
