Question

Molecular interactions between molecules is in order :

• A. solid < liquid < gas
• B. solid < gas < liquid
• C. gas < liquid < solid
• D. liquid < solid < gas

Answer 1

Answer: (C)

gas < liquid < solid

The gas molecules are far apart from each other. So, molecular interactions between gas molecules are minimum.
In liquid, they are nearer so forces of attraction are more.
In solids, the molecules are yet closer. So the forces of attraction between the molecules are maximum.
So, C is the correct answer.
