Under similar conditions of temperature ...

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 least , hence of sound in `H_(2)` shall be maximum.
