The speed of sound in hydrogen is `1270 ms^(-1)` at temperature T. the speed at the same T in a mixture of oxygen and hydrogen mixed in a volume ratio 1:4 will be ?
A
520 m/s
B
585 m/s
C
615 m/s
D
635 m/s
Text Solution
Verified by Experts
The correct Answer is:
D
`1270=sqrt((gammaP)/(rho))` Now, density becomes `4 rho`. So, `sqrt((gammaP)/(4rho))=sqrt((rP)/(rho))xx1/2=1/2xx1270=635 m//s`
