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 (C_p/C_v) ρ = specific weight of the gas)

ANS:B - 1/p

In the case of sound waves traveling through a gas, the velocity (v) of the gas is not directly proportional to the temperature (T) of the gas. Instead, the velocity of sound (v) in a gas is given by the equation: v=ρy⋅P​​ Where:

• T = Absolute temperature of the gas (not directly proportional to velocity).
• P = Absolute pressure of the gas.
• y = Ratio of specific heats (Cv​Cp​​).
• ρ = Specific weight of the gas (reciprocal of density, not directly proportional to velocity).
