When the temperature of the air is at 25 C, the velocity of a sound wave...

[Jody T]

...through the air is approximately? 320 m/s332 m/s347 m/s357 m/s

[Pranay C]

320 m/s(at 32 deg temp its 330. speed decreases as density decs.)

[PleaseRedirect]

347 m/sThere is an approximation for temperatures near 0 C. speedsound = 331.3 + 0.606(temperature)so speedsound(25 C) = 331.3 + 0.606*(25) == 347 C

sound velocity is 340 m/sec at 15Csound velocity is proportional to the square root of the absolute temperature in kelvinv1/v2 = (k1/k2)^(1/2)k1 = 15 + 273.15= 288.15v1 = 340 m/sect2 = 25 + 273.15= 298.15340/v2 = (288.15 / 298.15) ^ (1 / 2)v2 = 340 * (298.15 / 288.15) ^ (1 / 2)v2 = 345.85closer to 347 m/sec
