In moist or humid air, we can see a small (0.1% to 0.6%) increase in the speed of sound over dry air. The reason is that water molecules are less dense than molecules of nitrogen (N2) and oxygen (O2), which they will displace to a small degree. And less dense gases permit sound to travel faster because they have a lower shear. In a less dense gas, the gas "particles" (atoms or molecules) can "move more quickly" as individual particles to transfer the energy of the sound wave than the "particles" of a more dense gas. Note: Recall that nitrogen and oxygen in the air exist as diatomic molecules. There are two atoms hooked up in a kind of chemical "buddy system" here, and the gas is found this way. Wikipedia has more information, and a link is provided.

Explain the factors that affect the speed of sound?
The speed of sound is influenced by the medium it is traveling through. It increases in denser mediums such as solids and liquids, and decreases in less dense mediums like gases. Temperature also plays a role, as sound travels faster in warmer air and slower in colder air. Additionally, humidity can affect the speed of sound, with higher humidity levels typically resulting in a slightly faster speed.
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.
What factors affect the speed of sound in air?
The speed of sound in air at 20 degrees Celsius (68 degrees Fahrenheit) is 343 metres per second. That is 1126.5 feet per second. Notice: The speed of sound changes with temperature and a little bit with humidity − but not with air pressure (atmospheric pressure). The words "sound pressure at sea level" are incorrect and misleading. The temperature indication, however, is absolutely necessary.
What can affect the speed of sound?
The speed of sound c depends on the temperature of air and not on the air pressure!The humidity of air has some negligible effect on the speed of sound. The air pressureand the density of air (air density) are proportional to each other at the same temperature.
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.
How does each factor affect transmission of sound waves?
Pressure does not make any change in the speed of sound But temperature affects it. Velocity is proportional to the square root of kelvin temperature Humidity also affects the speed of sound. Higher the humidity more the speed
What speed does sound travel through a gas?
Sound travels through each medium (and each gas) at different velocities.In air, sound travels at an approximate speed of 330 m/s.Factors such as temperature and humidity also affect the speed of sound.

What are some Factors that affect speed of sound in air?
Think mainly of the temperature and a little bit of the humidity. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature in °C. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
How does temp and humidity change the speed of sound?
Yes, it affects the density of air and thus the speed of sound in air.

What affcts the speed of soundwaves in the air?
Primarily air density, so temperature, pressure, and vapor content are all factors, since they all affect air density.
What does not affect the speed of sound in air?
I think you're looking for a change in medium - that is to say, the frequency of a sound wave does not change as it passes from one material to another (like when sound travels from air to water), although it does affect speed, changing the wavelength.
