Question

What is the speed of sound in air if its temperature is 560°C

Answer 1

The formula for the speed of sound in air is the following:

$$c = 331m/s +0.6\dfrac{ m}{s\cdot \degree C}\cdot T$$

where $T = 560\degree C$.

Thus, obtain:

$$c = 331m/s +0.6\dfrac{ m}{s\cdot \degree C}\cdot 560\degree C = 667 m/s$$

Answer. 667 m/s.
