CHM 101 Chemical Bonding and Intermolecular Forces Objective Question

Question

Why do liquids have a fixed volume but take the shape of their container?
Options
A Particles are far apart and move freely
B Particles are close together but can move past each other; attractive forces maintain volume but allow shape change
Correct Answer
C There are no forces between particles in liquids
D Liquids are compressible
Correct Answer

Option B is the correct answer.

Detailed Explanation

Liquids have a fixed volume because the particles are close together and have significant attractive forces that maintain a constant volume. However, they take the shape of their container because the particles can move past each other and are not held in fixed positions.

Hint

Liquid particles can slide past one another while remaining close together.
