Question

For every one degree celsius rise in temperature, the speed of sound in air increases by nearly:

Answer 1

Air temperature, on the other hand, can cause measurable distance errors. The speed of sound increases by 0.6 meters per second (m/s) for every degree-Celsius (°C) increase in temperature.

Answer 2

At 0° Celsius the speed of sound in U.S. textbooks is 331.3 m/s. At 20° Celsius the speed of sound then is 343.21 m/s, rounded 343 m/s.
