velocity
of sound v is proportional to the square root of the absolute temperature T of the
ideal gas through which it travels. This is valid for ideal gases or air.
v α √T
v2 / v1 = √(T2 / T1)
v1 = 339 m/sec T1 = 273.15 + 15 = 288.15 °K
v2 = ? T2 = 273.15 + 115 = 388.15 °K
v2 = 339 m/s * √(388.15 / 288.15) = 393.45 meters/sec
v α √T
v2 / v1 = √(T2 / T1)
v1 = 339 m/sec T1 = 273.15 + 15 = 288.15 °K
v2 = ? T2 = 273.15 + 115 = 388.15 °K
v2 = 339 m/s * √(388.15 / 288.15) = 393.45 meters/sec
