Sound travels faster and more efficiently through liquids then through gases (whales can communicate for hundreds of kilometers)
Sound travels faster and more efficiently through solids then either liquids or gases (ear to a railroad track to hear an oncoming train...don't try this at home).
Exotic states of matter like neutron stars may be "best" for sound.
That's because sound is a compression wave. It needs a medium to travel through. The best mediums are dense, like metal and concrete. Liquids are okay. Gasses are the worst. Sound will not travel in space because there's no medium for sound to travel through.
If by best you mean fastest and/or furthest, than sound travels better through liquid. This is because the speed (and distance) of sound is dependent on the density of the medium it is traveling through. Since sound waves travel better with compression, they move faster in more solid mediums because of the mediums' tightly packed molecules.
i think you need a solid liquid and gas first to do this project
It travels best through solids
solid
It travels best through solids
Sound travels the best through a solid. Since the molecules in a solid are closer together than in a gas or liquid the sound waves don't have to travel as far to reach the next molecule.
the matter inside is bunched together so sound travels best through a solid.
Surprisingly no. Air is a gas which means that the molecules are far apart. Even a liquid is better that air for sound to travel through because the molecules are closer together. But, a solid is the best for a sound to travel through. This is because the molecules are very close together so the vibration is transferred much quicker though the material.
liquids.
Sound travels the fastest through non-porous solids.
Spongy materials are the most difficult for sound to travel through. Vacuum is the best acoustic insulation but it doesn't really count for the purpose of this question, since it is not a material but a lack of material.
