CHM 101 Chemical Bonding and Intermolecular Forces Objective Question
Take CBT

Question

Why do liquids expand when heated?
Options
A The particles increase in size
B The increased energy of particles allows them to exist at greater distances from each other because intermolecular forces remain constant
Correct Answer
C The particles lose mass
D The attractive forces between particles increase
Correct Answer

Option B is the correct answer.

Detailed Explanation

Liquids expand when heated because the particles gain kinetic energy and move more vigorously. This increased motion allows particles to exist at greater distances from each other, while the intermolecular forces remain constant, resulting in an overall volume increase.

Hint

Increased particle motion overcomes intermolecular attractions.
