Question

In which type of material will sound generally travel the fastest?
a vacuum
solids
liquids
gases

Answer 1

faster in solids then liquids then gases..sound needs a material medium to propagate so cant travel in a vacuum

Answer 2

ya what he said ----^
if you think a little more about it, sound is travelling faster when the molecules are placed closer together, so the forced produced by the vibration is more easily passed onto the molecules beside it,
so Solids have molecules closest then liquid then gasses, and vacuum where nothing is present, sound has no molecule to effect and pass on the vibrations

Answer 3

i don't think THATS why its true.. i think the reason it travels faster is because the force of attraction in the molecules of solids are very high.. this is the restoring force in a simple harmonic motion..
if the restoring force is high then definitely the accelerations are high and hence they travel fast

Answer 4

interesting

Answer 5

but water has hydrogen bonding and isnt that considered the highest attraction bonds
