How much in ...

Question

How much (in $m s^{- 1}$ ) is the change in velocity of sound in air due to $1^{o} C$ rise in temperature?

Open in App

Solution

Speed of sound in air is
$V = 331 + 0.6 (T)$
So the speed of sound at $i$ rise
So let us assume the speed of sound at $T = 0$ initially
Now, when there is $T = 0$
$V = 331$
When $T = 1^{o}$
$V = 331 + 0.6$
$∴$ rise $= 0.6 m / s$
