Question

Speed of sound is maximum in-

• A. Solids
• B. Liquid
• C. Both solid and liquid
• D. None of these.

Answer 1

The correct option is A

Solids

1. Speed of sound in a medium depends upon the following factors-

• Closeness of molecules.
• Density.

1. Since molecules are tightly closed in solids, as compared to liquids and gases, Sound will have a maximum speed in it.
2. Molecules of liquids are loosely packed as compared to solids, so the sound will have a lesser speed in liquids as compared to solids.
3. Molecules of gases are more loosely packed as compared to solids and liquids both, so the sound will have a lesser speed in gases as compared to both solids and liquids.

Hence, option (A) is correct.
