CHM 101 Chemical Bonding and Molecular Structure Objective Question

Question

Why do gases have low densities compared to solids and liquids?
Options
A Gas particles have very small masses
B Gases have large intermolecular spaces, resulting in large volumes relative to their mass
Correct Answer
C Gas particles are not affected by gravity
D Gases have strong intermolecular forces
Correct Answer

Option B is the correct answer.

Detailed Explanation

Gases have low densities because they have large intermolecular spaces. For a given mass, gases occupy much larger volumes than solids or liquids, resulting in lower density (mass per unit volume).

Hint

Density depends on both mass and volume; gases have large volumes.
