Question

At what temperature will the speed of sound in air be doubled than the speed of sound in air at 22 degree Celsius?

Answer 1

Temperature and the speed of sound
v = 331m/s + 0.6m/s/C * T

speed of sound in air at 22 degree Celsius = 331 + 13.2 = 344.2 m/s

Doubling the speed : 688.4 m/s
to get the temperature:
331m/s + 0.6m/s/C * T = 688.4 m/s
Temperature = 595.66 oC
