CHM 101 Chemical Bonding and Molecular Structure Objective Question

Question

What property of gases allows them to diffuse and mix completely?
Options
A High density
B Large particle size
C Perpetual motion of molecules at very high velocity and large intermolecular spaces
Correct Answer
D Strong intermolecular forces
Correct Answer

Option C is the correct answer.

Detailed Explanation

Gases diffuse readily because their molecules are in perpetual, high-velocity motion and there are large intermolecular spaces. These spaces allow gas molecules to move between one another, leading to complete homogeneity (mixing).

Hint

Rapid random motion and empty space between particles facilitate mixing.
