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.
The speed of sound in dry air at 20°C is about 330 m/sec. Humidity has a small effect on speed.
It 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.
At 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.
Sound travels more quickly through lower altitudes and warmer air. The speed of sound through air varies from 720-770 miles per hour.
about 768 mph
Helium: 965 m/s
Water: 1482 m/s
Steel: 5960 m/s
Propane Has a molar mass higher than air. So air travels slow in propane.
Solid
Sound waves travel through matter, whether solid, liquid, or gas. They do not travel through vacuum.
They travel faster through solids
Only by longitudinal mode
No. Sound waves must travel through a medium, such as air, liquid, or a solid.
Solid
A liquid
Sound waves travel through matter, whether solid, liquid, or gas. They do not travel through vacuum.
They travel faster through solids
Only by longitudinal mode
No. Sound waves must travel through a medium, such as air, liquid, or a solid.
Solid. Because it's more dense.
No. Sound will travel through any sort of matter, gas, solid, or liquid.
Sound can be transmitted through all mediums (liquid, solid, gaseous) except vacuum.
It travels through all three, but at different speeds.
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
Sound waves travel through the three states of matter (gas, liquid and solid) by vibrations.
