Question

write formula to find velocity of Sound​

Answer 1

Answer:

If the temperature is TC = 20 °C (T = 293 K), the speed of sound is v = 343 m/s. The equation for the speed of sound in air v = √γRTM can be simplified to give the equation for the speed of sound in air as a function of absolute temperature: v=√γRTM=√γRTM(273K273K)=√(273K)γRM√T273K≈331m/s√T273K.

Answer 2

${\bold{\green{\underline{\underline{Velocity \: of \: Sound :-}}}}}$

$\sf \frac{The \: square \: root \: of \: (the \:Coefficient \: ratio \: of \: specific \: heats) × the \: pressure \: of \: the \: gas}{The \: Density \: of \: the \: medium }$

☆ Mathematically :-

$\boxed{V = \frac{\sqrt{ \gamma \times p} }{ \rho} }$

Where,

V = velocity of sound

$\gamma$ = Specific heat ratio

P = pressure

$\rho$ = Density

$\sf\pink{Sound \: always \: travel \: in \: a \: medium. }$

So,

$V _{solids } > V _{liquids } > V _{gases }$

Velocity of Sound is maximum in solids and minimum in gases.
