Question

What is the speed of sound in dry air at 20 degrees Celsius?

Answer 1

The speed of sound in dry air at 20 degrees Celsius is approximately 343 meters per second (m/s) or about 1,125 feet per second (ft/s). This speed can vary slightly depending on factors such as humidity and atmospheric pressure, but 343 m/s is a commonly accepted average value for sound speed in dry air at that temperature.
