The speed of sound in air at NTP is 340 m/s. What will be the speed of sound in hydrogen at `500^(@)C` temperature and 2 atmospheric pressure ? Assuming air is 16 times heavier than hydrogen.

Explanation

To find the speed of sound in hydrogen at 500°C and 2 atmospheric pressure, we will follow these steps:

### Step 1: Understand the relationship between speed of sound and density
The speed of sound \( V \) in a medium is inversely proportional to the square root of its density \( \rho \):
\[ V \propto \frac{1}{\sqrt{\rho}} \]
