The speed of sond in air is `332m//s` at NTP. What will be its value in hydrogen at NTP, if density of hydrogen at NTP is `1//16th` that of air ?

Text Solution

Verified by Experts

As, `v=sqrt((gammaP)/(rho))` , taking `gamma` and P same for air and hydrogne , we get
`(v_(H))/(v_(a))=sqrt((rho_(a))/(rho_(H)))=sqrt((rho_(a))/(1//16rho_(a)))=4`
`v_(H)=4v_(a)=4xx332=1328m//s`
