Question

How does the speed of sound in air vary with temperature?

March 28, 2024

Answer

The speed of sound is directly proportional to the square root of temperature of the medium. It increases by about 0.61 m s^-1 (or 61 cm per second) for each 1°C rise in temperature (provided that the rise in temperature is not very large).

i.e.,

V_t = V₀ + 0.61t
