What is the degree of freedom of gas? If at STP, the velocity of sound in it is 330 m/s, gas density = 1.3 mg/`cm^3`

Explanation

To find the degree of freedom of a gas given the velocity of sound, density, and conditions at standard temperature and pressure (STP), we can follow these steps:

### Step 1: Write the formula for the velocity of sound in a gas.
The velocity of sound \( v \) in a gas is given by the formula:
\[ v = \sqrt{\frac{\gamma P}{\rho}} \]
where:
