At constant pressure, out of `H _(2) and O_(2)` gas in which gas speed of sound is greater ?

Text Solution

Verified by Experts

At constant pressure, speed of sound in a given gas is `v prop (1)/(sqrt rho) (because v = sqrt (( gamma P)/(rho )))`
We know that `rho_(H2) lt rho _(O2) implies v _(H2) gt v _(O2)`
