The velocity of sound in air at `20^(@)C` is `340ms^(-1)`. Keeping the temperature constant, what will be the velocity of sound in air when the pressure of the gas is doubled?

Explanation

To solve the problem of finding the velocity of sound in air when the pressure is doubled while keeping the temperature constant, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the relationship of sound velocity with pressure**: The velocity of sound in a gas is given by the formula:
\[ V = \sqrt{\frac{\gamma P}{M}} \]
