The speed of sound in dry air at 20°C is about 330 m/sec. Humidity has a small effect on speed.
In most gasses the speed of sound depends primarily on the temperature and, of course, the type of gas. It does not depend on pressure.
The formula for the speed of sound is, c = sqrt( gamma * pressureabsolute / density ), where gamma is the ratio of specific heats of the gas at a constant-pressure to the gas at a constant-volume(Cp / Cv).
For gasses with near ideal gas behavior, density is proportional to pressure, so the speed of sound is independent of pressure. Air, and its constituent gasses, oxygen, nitrogen, carbon dioxide, plus helium and others, have very nearly ideal gas behaviors near room temperature and above. Only when a gas is near its condensation point does the formula fail, as it would with water vapor.
In other extreme cases, such as very high frequency sound or shock waves, deviation from the ideal case can also be observed.

∙ 13y agoIt will travel through the gases fairly slowly, through liquids a lot faster and when they go through solids they are very fast.
It depends on the temperature and its molecular weight ( among other things ) of the gas, the density, temperature, pressure etc... of the liquid and the density and internal structure of the solid.

∙ 8y agoAt 20 degrees C, and 1 atmosphere pressure, the speed of sound in propane gas is 258 meters/ second. This is slower than the 343.59 m/sec in air. The speed of sound in LIQUID propane is different.

Will sound travel fastest through a liquid solid or gas?
Solid
Where do sound waves travel through?
Sound waves travel through matter, whether solid, liquid, or gas. They do not travel through vacuum.
Do sound waves travel faster threw liquid or solid?
They travel faster through solids
How does sound travel through solid liquid and gases?
Only by longitudinal mode
Can sound waves travel without a meduim?
No. Sound waves must travel through a medium, such as air, liquid, or a solid.
Will sound travel fastest through a liquid solid or gas?
Solid
Does sound travel more quickly through a liquid or a solid?
A liquid
Where do sound waves travel through?
Sound waves travel through matter, whether solid, liquid, or gas. They do not travel through vacuum.
Do sound waves travel faster threw liquid or solid?
They travel faster through solids
How does sound travel through solid liquid and gases?
Only by longitudinal mode
Can sound waves travel without a meduim?
No. Sound waves must travel through a medium, such as air, liquid, or a solid.
Does sound travel faster through a solid liquid or gas and how?
Solid. Because it's more dense.
Does sound only traveled through gases?
No. Sound will travel through any sort of matter, gas, solid, or liquid.
What medium can sound travel through?
Sound can be transmitted through all mediums (liquid, solid, gaseous) except vacuum.
Does sound travel through solid liquid or gas?
It travels through all three, but at different speeds.
Why do you think sound cannot travel through vacuum?
Sound travels by vibrating through matter (solid, liquid, gas) A vacuum is the absence of matter and with out matter there is nothing for sound to travel through
How do sound waves travel trough matter?
Sound waves travel through the three states of matter (gas, liquid and solid) by vibrations.
