What happens to the speed of sound in air when the pressure increases at a constant temperature
A
Unchanged
B
Increase
C
Reduce
D
Varies
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
The speed of sound in air at a constant temperature is primarily dependent on the temperature of the air rather than the pressure. At a constant temperature, changes in pressure do not significantly affect the speed of sound.
