Question

What is the speed of sound at a temperature

of 56°C?
A: 316 meters/second
B: 331 meters/second
C: 365 meters/second
D: 373 meters/second

Answer 1

Answer: The correct answer is Option C.

Step-by-step explanation:

Speed of sound is directly related to the temperature.

The relation between speed of sound and temperature is given by the equation:

`\text{Speed of sound}=331.5+0.60T(^oC)`

where, T = absolute temperature

Putting T = 56°C in above equation, we get:

`\text{Speed of sound}=331.5+0.60* 56=365.1m/s`

Hence, the correct option is Option C.
