Question

Determine the difference in the speed of sound in hydrogen at 0 degrees Celsius and in air at 30 degrees Celsius. Also indicate if is it faster or slower

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.
