The velocity of sound in a tube containing air at 27°C and a pressure 76 cm of mercury is `330"m s"^(-1)`. What will be the velocity of sound when pressure is increased to 100 cm of mercury and the temperature is kept constant?

Explanation

To solve the problem of finding the velocity of sound in a tube containing air when the pressure is increased from 76 cm of mercury to 100 cm of mercury while keeping the temperature constant, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Given Values**:
- Initial pressure (P1) = 76 cm of Hg
- Final pressure (P2) = 100 cm of Hg
- Initial velocity of sound (V1) = 330 m/s
