Ali Hunt · Answer 1

The speed of sound at different temperatures may be calculated through the following equation,

v = 331 + 0.6T

where v is the speed and T is the temperature in °C.

Substituting the known values,

0°C : v = 331 + (0.6) (0) = 331 m/s

30°C: v = 331 + (0.6) (30) = 349 m/s

Thus, the higher the temperature, the greater is the speed of sound.
