The speed of sound in air changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure).
Speed of sound c = 331.3 + 0.606 × ϑ
At the temperature ϑ = 20°C the speed of sound is c ≈ 331 + (0.6 × 20) = 343 m/s.

Why does speed of sound depend on the temperature of a medium through which sound waves travel?
Speed of sound increases with the increase in temperature of the medium .In fact the speed of sound is directly proportional to the square root of absolute temp. of the medium.
What process is primarily responsible for the increase of speed and sound on a rail road track?
The speed of sound depends on the medium. There is no particular process that will simply increase the speed of sound.
How can the speed of sound through a gas increase?
The speed of sound may vary, depending on:* On the type of gas * On the temperature * On the pressure
What happens to the speed of sound if the temperature of the medium increases?
Speed of sound increase when temperature increases.
Why does the speed of sound depend on the temperature of the medium?
Speed of sound increases with the increase in temperature of the medium .In fact the speed of sound is directly proportional to the square root of absolute temp. of the medium.
Does the speed of the sound change from medium to medium?
Dependence of the speed of sound on the properties of the medium: The speed of sound is variable and depends mainly on the temperature and the properties of the substance through of which the wave is traveling. For example, in low molecular weight gases, such as helium, sound propagates faster compared to heavier gases, such as xenon. In a given ideal gas the sound speed depends only on its temperature. At a constant temperature, the ideal gas pressure has no effect on the speed of sound, because pressure and density (also proportional to pressure) have equal but opposite effects on the speed of sound, and the two contributions cancel out exactly. In non-ideal gases, such as a van der Waals gas, the proportionality is not exact, and there is a slight dependence on the gas pressure, even at a constant temperature. Humidity also has a small, but measurable effect on sound speed (increase of about 0.1% to 0.6%), because some oxygen and nitrogen molecules of the air are replaced by the lighter molecules of water.

Does the speed of the wave change when you increase the tension of the spring?
No. The speed of sound is dependent on air pressure and temperature.
What is the measurement mach?
Mach is the speed of sound in that medium, and is known as Mach 1. It will vary according to pressure and temperature. [More correctly, it is the dimensionless number relating the speed of an object to that of sound in that medium.] Mach does not have units associated with it, such as mph or kmph.
Why does speed of light change in different mediums?
Dependence of the speed of sound on the properties of the medium: The speed of sound is variable and depends mainly on the temperature and the properties of the substance through of which the wave is traveling. For example, in low molecular weight gases, such as helium, sound propagates faster compared to heavier gases, such as xenon. In a given ideal gas the sound speed depends only on its temperature.

As the temperature of a medium increases the rate of speed of sound through the medium what?
The speed of sound through the medium also increases.
What factors affect the speed of wave?
Some factors that affect the speed of sound waves are density of medium, temperature, direction of wind, and humidity. Remember that a sound wave is just a pressure disturbance that travels through a medium by particle interactions. The nature of the medium will affect the sound waves velocity.
How fast is the sound barrier?
I guess you refer to the speed of sound. The speed of sound depends on the material sounds goes through, as well as temperature, pressure, humidity, among others. For example, the speed of sound in air is around 350 meters/second; in some other materials it can be several times as fast.
