The heat capacity ratio of a gas determines the speed of sound in it through the formula

Question:

The heat capacity ratio of a gas determines the speed of sound in it through the formula cs = (γRT/M)1/2, where γ = Cp /CV and M is the molar mass of the gas. Deduce an expression for the speed of sound in a perfect gas of

(a) Diatomic,

(b) Linear triatomic,

(c) Nonlinear triatomic molecules at high temperatures (with translation and rotation active). Estimate the speed of sound in air at 25°C.
