The speed of sound as measured by a student in the laboratory on a winter day is 340 m s -1 when the room temperature is 17°C. What speed will be measured by another student repeating the experiment on a day when the room temperature is 32°C?

Question

Philoid · Accepted Answer

Given:
Velocity of sound
Temperature

Let the velocity of sound at a temperature be .

Relation between velocity and temperature:

So,

⇒

On substituting the respective values, we get:

Hence, the final velocity of sound is 349 m/s.
