Question

You adjust the temperature so that a sound wave travels more quickly through the air. You increase the temperature from 30°C to 36°C. What's the velocity of the sound wave at this new temperature?

A. 335.6 m/s
B. 352.6 m/s
C. 350.0 m/s
D. 344.0 m/s

Answer 1

The answer is B 352.6 m/s

Answer 2

Answer is: the velocity of the sound wave is B. 352.6 m/s.

T₁ = 30°C; initial temperature.

T₂ = 36°C; final temperature.

The formula of the velocity of the sound: v = 331 m/s + 0.6T.

v = 331 m/s + 0.6 m/s°C · 36°C.

v = 352.6 m/s.

When the temperature of the air increases, the speed of sound also increases at a rate of 0.6 m/s for each celcius degree.
