The constant `gamma` of oxygen as well as for hydrogen is 1.40. If the speed of sound in oxygen is `470 ms^-1,` What wil be the speed in hydrogen at the same temperature and pressure?

Answer

1880 m/s

Explanation

Sound speed in gases is given as
`v = sqrt((gammaRT)/(M)) `
`(v_(1))/(v_(2)) = sqrt((M_(2))/(M_(1)))`
`v_(H_(2)) = v_(o_2) sqrt((m_(0_2))/(M_(H_2)) ) = 470 xx sqrt((32)/(2))`
= 1880 m/s
