Under similar conditions of temperature and pressure, In which of the following gases the velocity of sound will be largest :-

A

`H_2`

B

`N_2`

C

`He`

D

`CO_2`

Text Solution

Verified by Experts

The correct Answer is:
A
The speed of sound in air is `v = sqrt((gamma RT)/(M))`
`gamma/M` of `H_2` is greatest in the given given gesses, hence speed of sound in `H_2` shall be maximum.
