Which prediction for the speed of sound in air at 60°C is best supported by
the data in the table?
A. 325 m/s
B. 345 m/s
C. 355 m/s
D. 365 m/s
speed of sound (m/s) = 331.5 + 0.60 T(°C) For example, the speed of sound in air is 386 m/s at 100 °C. The sound of speed in air is increased by 0.60 m/s for each increase of degree in air temperature. The speed of sound is faster at higher temperatures because molecules collide more often.
