CHM 101 Chemical Bonding and Intermolecular Forces Objective Question

Question

What happens to the particles of a liquid when it is cooled and freezes?
Options
A Particles gain kinetic energy and move faster
B Particles lose kinetic energy, attractive forces strengthen relative to particle energy, and particles become restricted to fixed positions
Correct Answer
C Particles become gas directly
D Particles break apart
Correct Answer

Option B is the correct answer.

Detailed Explanation

When liquids are cooled, particles lose kinetic energy. The attractive forces become stronger in comparison to the particle energy, causing the particles to become restricted to fixed positions as they transition from the liquid to the solid state.

Hint

Cooling reduces particle motion until forces lock particles in place.
