"The velocity of sound is generally greater in solids than in gas at N.T.P." Why?

Explanation

To understand why the velocity of sound is generally greater in solids than in gases at normal temperature and pressure (NTP), we can analyze the relationship between the velocity of sound, elasticity, and density.

### Step-by-Step Solution:

1. **Understanding the Velocity of Sound Formula**:
The velocity of sound (v) in a medium is given by the formula:
\[
v = \sqrt{\frac{E}{\rho}}
