The ratio of the velocity of sound in a monatomic gas to that in a triatomic gas having same molar mass , under similar conditions of temperature and pressure , is ………….

Options

A. 1.12
B. 1.25
C. `1.50`
D. `1.6`

Answer

A

Explanation

`v = sqrt((gamma RT)/(M)) implies sqrt((gamma_("mono"))/(gamma_("tri"))) = sqrt(((5//3))/((4//3))) = sqrt(1.25) = 1.12`
