Velocity of a gas in sound is not proportional to (where, T = Absolute temperature of the gas. P = Absolute pressure of the gas. y = Ratio of specific heats (Cp/Cv) ρ = specific weight of the gas) ?
Correct answer: C. 1/√P
- A. √T
- B. √y
- C. 1/√P
- D. 1/√ρ
Explanation
The sound speed is proportional to √(γP/ρ), or, for an ideal gas, to √T. It is therefore proportional to 1/√ρ but not to 1/√P, since increasing pressure increases sound speed at fixed density.
