Question

The speed of sound in air would become double than its speed at 10C at a temperature of?

Answer 1

At 1132 K   or = 859 °C The speed of sound in air would become double than its speed at 10°C

Explanation:

speed of sound in air varies as

V∝ $\sqrt{T}$ ........................... eq 1  

The Temperature  (T) must be in kelvin :

V₂ = 2 V₁

$\sqrt{T_{2} }$ = 2  $\sqrt{T_{1} }$

T₁ = 10 ° = 283 K

$\sqrt{T_{2} }$ = 2 * $\sqrt{283}$

 T₂ = 4 * 283 K

      =  1132 K

      or = 859 °C

Answer 2

Explanation:

speed of sound in aluminium at 20 Celsius is
