The velocity of sound in air at 14°C is 340 m/s. What will it be when the pressure of the gas is doubled and its temperature is raised to 157.5°C?

Answer:

416.40

Solution:

$v \propto T$ and is independent of pressure. $T_{1} = 287$ K, $T_{2} = 430.5$ K. $v = 340 430.5/287 = 340 1.5 = 416.4$ m/s.
