The speed of sound in a gas does not depend on pressure.
See related links.
There are limits to the validity of this statement because it is valid for gasses that behave as "ideal" gasses. Thus, when near a pressure and temperature that is close to the point that the gas will condense into a liquid, this statement fails. For air, at all the temperatures which we experience, the speed of sound in air is independent of pressure.
What else can I help you with?
How does the pitch of a sound affect its speed?
The pitch of a sound, which is determined by its frequency, does not affect its speed. The speed of sound in air at room temperature is roughly 343 meters per second. This speed is independent of the pitch of the sound wave.
How does the decreasing the gas volume affect the pressure of a gas?
The pressure increase.
How does the speed of sound relate to temperature elasticity and density?
The speed of any mechanical wave depends on the density of the medium. Since solids are the densest, the speed of sound is minimum in solids. It is the maximum in gases, since the medium is the least densest.
Does the speed of sound depend on the loudness?
The answer is: No! In an ideal gas, which air can be considered, the speed of sound is given by:- c= √(γ(p/ρ)) where γ is the abiabatic index, p is the pressure and ρ is the density. and p= ρRT/M where R is the ideal gas constant, M is the Molar mass and T is the absolute temperature. From his equation, if temperature and mass are constant -, one can see that p is proportional to ρTherefore if atmospheric pressure is doubled so is the density Hence p/ ρ is constant. Therefore atmospheric pressure does not affect the speed of sound. However, increase in temperature will lead to an increase in speed. At high altitudes, the temperature is significantly lower, and hence the speed of sound is lower.
Does the speed of sound depend on its density?
The speed of sound c in air under normal conditions is only dependent on the temperature. It is independent of the air pressure p.Reason: The air pressure p and the air density rho are proportional to each other at the same temperature. Hence, the speed of sound in air, which depends on the ratio of p to rho, is constant. Therefore the speed of sound in air is the same on a mountain peak as it is at sea level, provided that the temperature is the same.On the other hand, if you change from one gas to another, the speed will depend on density. For example, Argon gas and Helium gas at the same temperature and pressure will have very different densities and this will result in very different speeds for sound. In that case, the speed of sound is proportional to the inverse of the square root of the molecular mass. For more details see the related links.The speed of sound in solids will be much faster than in a liquid, but there is no simple relationship to the density in that case. For example, iron and aluminum have very different densities, but almost the same speed for 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
How does the pitch of a sound affect its speed?
The pitch of a sound, which is determined by its frequency, does not affect its speed. The speed of sound in air at room temperature is roughly 343 meters per second. This speed is independent of the pitch of the sound wave.
What is the speed of sound in this gas?
The speed of sound in a gas depends on factors like temperature and pressure. In general, the speed of sound in air at room temperature is about 343 meters per second.
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.
How does the frequency of a sound wave depend on the pressure of the air?
The speed of sound is not greatly affected by pressure in an ideal gas. Air is not an ideal gas, so there may be some small effect, but temperature and humidity will be much more influential. ================================ Answer #1: The frequency of sound is completely determined by the source of the sound. Once the sound leaves the source, the frequency doesn't change.
What is called the ratio of gas velocity and the speed of sound in the gas at the same condition of pressure and temperature?
The Mach number
What is the speed of sound in gas?
speed of sound in gas is 332m per second
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.

What are the factors that affect the velocity of sound in a gas?
The velocity of sound in a gas is affected by factors such as the temperature, pressure, and density of the gas. In general, sound travels faster in gases with higher temperatures, higher pressures, and lower densities.
Do sound waves travel in high pressure?
Yes, sound waves can travel through substances with varying pressure levels. In general, sound waves can travel through both low and high-pressure environments, but the speed and characteristics of the sound wave may be affected by the pressure level of the medium through which it is traveling.
How does the temperature of a material affect the speed of a sound passing through?
on increasing of temperature, density goes low and it is known that density and speed of sound both are directly proportional hence speed of sound decrease when temperature increases esp in gas.
How does the decreasing the gas volume affect the pressure of a gas?
The pressure increase.
