Question

Temperature in the Rajasthan desert can reach 46 degree Celsius what is the velocity of sound in air at that temperature

Answer 1

Answer:

357.8m/s

Explanation:

Velocity of sound is given by

V=√(gamma)(p)/(rho)

Where ,

gamma is ratio of cp/cv

P is the pressure

Rho is density of air

Also PV= nRT so P is proportional to T therefore

V is proportional to √T

We know speed of sound at 273 k (Vo)is 331 m/s then ratio of Vt and Vo is given by ratio of√T/√To

Vt/Vo = (319)/(273)=1.080967

Vt=331(1.080967)

Vt=357.8m/s
