Speed of sound in an ideal gas depends on its________________?
Correct answer: A. Temperature
- A. Temperature
- B. Pressure
- C. Specific volume
- D. None of these
Explanation
The ideal-gas sound speed is a = √(γRT), so at fixed gas composition it varies with the square root of absolute temperature. Pressure and specific volume are not independent controlling variables for an ideal gas once temperature is specified.
