Question

Velocity of sound in air at 22C

Answer 1

i think the velocity of sound is
344m/sec

Answer 2

Thr speed of sound changes by 0.6 m/s for every 1 degree change in temperature.

So, we can derive the following formula-

Speed of sound at temp. T = 332 + (0.6T)

So, at 22 degree centigrade:
332 + (0.6 * 22) = 332 + 13. 2= 345.2 m/s.

So, speed of sound at 22 degrees is 345. 2m/s.
