Question

question 19 of 30 how does increasing the temperature of a liquid below the boiling point affect the motion of the particles in the liquid? a. the motion of the particles overcomes the forces holding the particles together. b. the particles move slower. c. the motion of the particles strengthens the forces between the particles. d. the particles move faster.

Explanation:

To solve this, we recall the relationship between temperature and particle motion. Temperature is related to the kinetic energy of particles. When temperature increases (below boiling point for a liquid), the kinetic energy of particles increases. Higher kinetic energy means particles move faster.

• Option A: Overcoming forces holding particles together happens at boiling (phase change to gas), not just increasing temp below boiling. Eliminate A.
• Option B: Increasing temp should increase, not decrease, particle speed. Eliminate B.
• Option C: Particle motion (kinetic energy) and intermolecular forces are different; increasing temp doesn't strengthen intermolecular forces. Eliminate C.
• Option D: Matches the concept that higher temp (more kinetic energy) leads to faster particle motion.

Answer:

D. The particles move faster.
