The speed of sound in air is approximately figured out by the formula …

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.
