The graph drawn between the velocity of sound in a gas and pressure of the gas at a given temperature is
The graph drawn between the velocity of sound in a gas and pressure of the gas at a given temperature is
Show Hint
Logic Tip: A classic trick question! Always remember that isothermal changes in pressure cause identical proportional changes in density. Thus, $P/\rho$ remains constant, meaning sound velocity only depends on temperature, not pressure.
