In general, sound travels faster in solids than in liquids, and faster in liquids than in gases.
While this might seem to imply that speed of sound drops with density, this is incorrect.
The speed of sound in gases of different types actually increases as density decreases, due to the lower inertia of the particles. Hydrogen has a speed of sound 6 times that of chlorine (1284 m/s vs 206 m/s), though chlorine is 36 times as dense. Sulfur hexafluoride is a very dense gas, with a low speed of sound around 150 m/s.
For a given gas, the speed of sound does not vary with pressure or density. It does vary with temperature, though. So cold air has a slower speed of sound than hot air. The boiling point of SF6
is −64°C, so it is still a gas at this temperature, which would drop the speed of sound to maybe 127 m/s.
Aerogels are solid, but the speed of sound is said to be around 70-100 m/s. They are also good absorbers of sound, though, so the sound does not travel far.

∙ 14y agoSound is the result of energy wave conductance from molecule to molecule, therefore in a high molecular density substance i.e. a solid, wave energy will transfer rapidly, FACT: sound travels faster in water than through air due to the distance between particles for energy transmission.
Sound would therefore travel slowest in a gaseous environment. In further detail a lighter gas will alow sound to travel slower than a heavier gas. i.e. Helium is lighter than oxygen.
Using this theory you could suggest that sound would travel slowest in a hydrogen gas based environment as hydrogen has the lowest molecular density.

∙ 9y agoSound / vibration waves will travel slowest in a lossy material with some compressibility. Foam polystyrene would be an example of such.
This material will have only a modest stiffness, and you may well be able to measure the velocity of sound using simple equipment. Another lossy and slow material would be plasticene.
One method would be to set up standing waves in the material, (e.g. from a loudspeaker driver or similar), and from this you may measure the velocity.
Sound waves travel fastest in Beryllium.

Why does sound not travel through space?
Sound does move through space. It doesn't move though empty space, i.e. a vaccuum. In outer space there is a vaccuum (though not necessarily a perfect vaccuum).Sound is caused by vibrations in a medium such as air (or water or wood). These vibrations compress and rarefy the medium. The vibrations move through the medium as waves.In a vaccuum, there is no medium thus there is no sound.
Particles of a matter move the slowest in a?
solid
What temperature does sound travel faster in?
That depends on the nature of the medium through which it is traveling and how that medium's density is affected (if it is affected at all) by its change in temperature. The denser the medium, the faster sound travels through it. For example, in a sealed chamber containing a gas, the speed of sound is not affected by temperature unless it gets cold enough for the gas to condense to a liquid. As long as it remains a gas, changes in temparature only affect its pressure, not its density.
Do sound waves particles move fast though a solid?
Yes, they do. Sound waves move fastest through solids, less fast through liquids, and slowest through gasses. This is because the molecules of solids are closer together, while those of gasses are further apart, creating more space that the waves must jump to move.
Through what material does sound travel slowest?
sound will travel through air (gas), the slowest. Because the molecules in the air are farther apart. Actually rubber it will travel through rubber the slowest. Air is second slowest. Age: 15 Name: Rachel Thanks for reading! <3
What medium does sound travel the slowest in?
Gases
Which kind of matter does sound waves move the slowest?
dry air
What can affect the speed at which sound travels?
The most relevant answer to this question is medium, the most prime factor affecting the rate of sound travel is the medium which carries the sound waves, sound is fastest in solids and slowest in viscous fluids.
Why does a sound wave travel the slowest in a vacuum?
Sound waves don't just travel the slowest in a vacuum, they don't travel at all. The reason is that sound waves, like all mechanical waves, need a medium to travel through.
What material can sound energy travel through slowly?
The more closely packed molecules are in a medium, the faster sound travels through the medium, so sound travels slowest through a gas under low pressure.
Why is sound traveled slowest through a solid?
It doesnt. Sound actually travels faster the denser the medium is because the molecules are packed closer together. So sound travels fastest in solids.

What is required to create sound?
vibration and a medium for it to move through
What is the slowest speed an object can move?
The slowest speed an object can move is zero.
Do light and sound require medium for transfer?
Light does not because of its' quantum nature. Sound does because it depends on varying the density of its' medium to move its' energy.
Douse sound waves require a medium to be able to move?
Yes.
What medium allows sound to move faster?
air, when compared to water
