Velocity of sound is greater in solids than gases because:
Correct answer: D. Elasticity of solids is very high
- A. Density of solids is high and elasticity is low
- B. Both density and elasticity are low
- C. Density is low and elasticity is high
- D. Elasticity of solids is very high
Explanation
Here is the explanation of the correct optionThe velocity of sound is greater than in gases primarily because solids have much higher elasticity. The high elasticity allows sound waves to move more quickly despite also solids having higher density. (Concept of atomic packing).

About Speed of Sound
The speed of sound depends on the properties of the medium, including its elasticity and density, and in gases it varies mainly with temperature. Questions connect speed with frequency and wavelength, compare sound in solids, liquids and gases, and distinguish the speed of propagation from the oscillating particles' motion.
