TextBook Solutions for Punjab School Education Board Class 12 Chemistry Chemistry I Chapter 1 The Solid State

Question 1

Why are solids rigid?

Solution

Solids are rigid because the internuclear distance between the molecules of a solid are very less and closely packed and their positions are fixed due to the strong forces of attraction between them.
