Question

A sound wave travels through a column of carbon monoxide at STP. Assuming a density of rho = 1.25 kg/m3 and a bulk modulus of β = 1.42 ✕ 105 Pa, what is the approximate speed (in m/s) of the sound wave?

Answer 1

v = 337.04m/s

Step-by-step explanation:

In order to calculate the speed of sound for the case of a carbon monoxide medium, you use the following formula:

`v=\sqrt{(\beta)/(\rho)}` (1)

v: speed of sound

β: bulk modulus = 1.412*10^5 Pa

ρ: density of the column of carbon monoxide = 1.25 kg/m^3

You replace the values of the parameters in the equation (1):

`v=\sqrt{(1.42*10^5Pa)/(1.25kg/m^3)}=337.04(m)/(s)`

The speed of the sound in the column of carbon monoxide is 337.04 m/s
