Why go sound travel faster in solids 보다 in liquids, and also faster in liquids 보다 in gases (air)? inquiry by: will certainly KAnswerSound is nothing much more than a local disturbance who propagation is facilitated by the collisions in between particles; this disturbance propagates ina logitudnal wave; imagine one molecule hitting the following molecule, and then the molecule hitting the next, and also so forth.The distances between molecules in solids are very small, i.e., solids are more dense - as compared to liquids and gases. Because theyare so close, than deserve to collide an extremely quickly, i.e. It takes less time for a molecule the the solid come "bump" into its neighborough. Solids room packed together tighter than liquids and also gases, hence sound travel fastest in solids. The ranges in liquids are shorter than in gases,but much longer than in solids. Liquids are an ext dense than gases, however less dense than solids, therefore sound travels 2nd fast in liquids. Gases are the slowest since they space the least dense: the molecules in gases are an extremely far apart, contrasted with solids and also liquids.Answered by: Jonathan AppleIf one solves the tide equation because that the propagation that sound, one find thatthe square of the sound velocity is proportional come the ratio of an elasticmodulus to the mass density of the material. Therefore, by a an easy densityargument, one have to conclude that the sound velocity is higher in gasesthan in solids and also liquids which, the course, is no true. The factor why thesound velocity is usually bigger in solids 보다 in liquids and usuallylarger in liquids 보다 in gases is because of the elastics constants of thematerial. What determines the elastic constants the a product is the interatomic bondstrength. The stronger the bond, the greater the elastic constants. In gases,the atoms are an extremely weakly external inspection together and the elastic constants are verylow. In solids, the atom are much more tightly bonded together, and also the elasticconstants are higher, ... That is many of the time. In part cases, someelastic constants the solids deserve to drop to practically zero and also the (shear) soundvelocity have the right to reach virtually zero. This deserve to happen, because that example, near astructural step transformation.Answered by: Andr" Moreau, Canada
