Question

Velocity of sound in a gas medium is 330 ms-1 . If the pressure is increased by 4 times what is the velocity of sound in the gas

Answer 1

Answer:

Velocity of sound remains the same in gas

Explanation:

According to Boyle's Law , at constant temperature,

velocity=root of P/ρ   (ρ=density)

P/ρ=PV/m=a constant

therefore, velocity  of sound is independent of the change in pressure
