Question

(☞ what is the speed of sound in gases ??​

Answer 1

Answer:

The speed of sound in air at 20oC is 343.2 m/s which translates to 1,236 km/h. The speed of sound in gases is proportional to the square root of the absolute temperature (measured in Kelvin) but it is independent of the frequency of the sound wave or the pressure and the density of the medium.

Answer 2

Explanation:

Speed of Sound in Gases

Gas ft/s m/s
