Speed of sound in air at 0 deg C is about
A100 m/s only
B300 m/s only
C332 m/s
D30 m/s only
Answer & Solution
Correct answer: C. 332 m/s
1. The chapter section on speed in different media gives this value.
2. At 0 deg C and standard pressure, sound moves at 332 m/s.
3. It rises about 0.6 m/s per deg C of temperature rise.
4. So option A is correct.
