Question

Speed of sound is greater in solids than in gases. Because :

• A. in solids transfer of energy from one particle to another takes more time
• B. in solids collision between the particles are less
• C. in solids particles are very close compared to gases
• D. all the above are true

Answer 1

The correct option is C in solids particles are very close compared to gases

Since the distance between the particles in solids is very less, those are very close to each other. Transfer of energy takes place in less time. So speed of sound in solids is large.
