Hello @kkanade , allow me to answer this one,

The speed of sound does not have a specific value but it depends on the medium. Indeed, it represents the velocity of propagation of a sound wave through a medium. Its more general expression, valid for all gases, is:

a = sqrt[ (dp/drho)_s ]

where s indicates an isentropic process.

A more commonly used expression, for the speed of sound, is the one for calorically perfect gases:

a = sqrt( gamma*R*T)

where

gamma is the ratio of the specific heats

R is the specific gas constant

T is the medium temperature

Hope that answers your question! ?
