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. 350.0 m/s
C. 352.6 m/s
D. 344.0 m/s

Answer 1

Answer;

C. 352.6 m/s

Explanation;

Velocity of sound is dependent on temperature. An increase in temperature, increases the velocity of sound.

To calculate the velocity of the sound wave, we use this formula:

V = 331 + [0.6*T]; Where V is the velocity and T represents temperature.

When the temperature is 36 degree Celsius, we have

V = 331 + [0.6 * 36]

V = 331 + 21.6 = 352.6

Therefore,

V = 352.6 m/s.
