Velocity of sound in air is

A

Faster in dry air than in moist air

B

Directly proportional to pressure

C

Directlyproportional to temperature

D

Independent of pressure of air

Text Solution

Verified by Experts

The correct Answer is:
D
As `v = sqrt((gammaP)/(rho)) ` as P changes, `rho` changes. Hence `(P)/(rho)` remains constant so speed remains constant.
