Since the density of air decreases with an increase in temperature, but the bulk modulus B is nearly independent of temperature, how would you expect the speed of sound in air vary with temperature?
Homework Answers
Speed of sound in gas is
v = sqrt(B/density)
The speed of sound depends on bulk modulus and density.
The Bulk modulus is not depending on temperature.
So the speed of sound depends only on density of air.
The speed of sound is inversely proportional to square root of density of air. The density of air decrease when the temperature increases. So the speed of sound increases with temperature.

A SCUBA diver produces a spherical air bubble with bulk modulus B = 1.2 x 10e5 Pa and radius r1 = 2.9 mm while exploring a shipwreck below the surface of the ocean. The air bubble rises to the surface of the ocean and expands to a radius r2 = 3.8 mm. What is the difference in pressure between the surface and at the SCUBA diver's depth, ( Psurface − P diver )?

The speed of sound in air (in m/s) depends on the temperature according to the approximate expression below, where TC is the Celsius temperature. In dry air the temperature decreases about 1°C for every 150 m rise in altitude. v = 331.5 + 0.607TC (a) Assuming this change is constant up to an altitude of 9000 m, how long will it take the sound from an airplane at 8800 m to reach the ground on a day when the ground...
