Does sound travel faster through a solid liquid or gas?
of course in solid. bcoz solids have closed particles. so it cn transmit sound waves more easily.
solid, as the particles are closer together and sound vibrations can pass quickly and easily from one particle to the next.
Liquid is the next and then air (because the particles are futher apart)
solid cause the molecules in the solid are more packed
Sound travels faster through a solid.
See, first make yourself clear with the concept of sound.
What is sound?
It is a wave..it is a kinda vibration.
How does it travel? It travels by setting the neighbouring particles into motion.
So, when the sound is travelling in air, where the particles are far apart, each particle which is set into motion has to travell a longer distance to clash with another particle and continue the motion.
Whereas in the solids, where the particles are near, the particles don't have to travel a long way, to reach another particles and set them into motion. So the sound takes lesser time in a solid.
In short, you can say, the denser the medium becomes, the faster the sound travels.
Sound needs particles to travel. That is why the sound cannot travel in vacuum(which does not have any particles)
The speed of sound or the speed of sound waves passing through an elastic medium varies with the medium employed (for example, sound waves move faster through water than through air), as well as with the properties of the medium, especially temperature. The term is commonly used to refer specifically to the speed of sound in air. At sea level, at a temperature of 21 °C (70 °F) and under normal atmospheric conditions, the speed of sound is 344 m/s (769 mph or 1238 km/h).
The speed of sound is sometimes used in describing the nature of substances .
Speed in solids:
The speed of sound in solids depends upon the elastic nature of the solid and feasibility of propagation of waves.If,
In a solid, there is a non-zero stiffness both for volumetric and shear deformations. Hence, in a solid it is possible to generate sound waves with different velocities dependent on the deformation mode.
In a solid with lateral dimensions much larger than the wavelength, the sound velocity is higher.
Speed in a liquid:
In a fluid the only non-zero stiffness is to volumetric deformation (a liquid does not sustain shear forces).
The speed of sound in water is of interest to those using acoustics as a tool in the oceans or lakes, e.g., for communication, mapping the ocean floor, or ocean acoustic tomography. . In fresh water, sound travels at about 1435 m/s.
In salt water, sound travels at about 1500 m/s. The speed of sound in seawater depends on pressure (hence depth), temperature (a change of 1 °C ~ 4 m/s), and salinity (a change of 1‰ ~ 1 m/s), and empirical equations have been derived to accurately calculate sound speed from these variables. Other factors affecting sound speed are minor. is due to Mackenzie (1981)
A simple empirical equation for the speed of sound in sea water with reasonable accuracy for the world's oceans is due to Mackenzie (1981)
c(T, S, z) = a1 + a2T + a3T2 + a4T3 + a5(S - 35) + a6z + a7z2 + a8T(S - 35) + a9Tz3
where T, S, and z are temperature in degrees Celsius, salinity in parts per thousand and depth in metres, respectively. The constants a1, a2, ..., a9 are:
a1 = 1448.96, a2 = 4.591, a3 = -5.304×10-2, a4 = 2.374×10-4, a5 = 1.340, a6 = 1.630×10-2, a7 = 1.675×10-7, a8 = -1.025×10-2, a9 = -7.139×10-13
with check value 1550.744 m/s for T=25 °C, S=35‰, z=1000m. This equation is accurate to O(0.2 m/s). See Technical Guides - Speed of Sound in Sea-Water for an online calculator.
Speed in ideal gases and in air:
In fact, assuming an ideal gas, the speed of sound c depends on temperature only, not on the pressure or density (since these change in lockstep for a given temperature and cancel out). Air is almost an ideal gas. The temperature of the air varies with altitude, giving in the speed of sound using the standard atmosphere - actual conditions may vary.
weird but true
Density is a measure of mass per unit of volume: kilograms per cubic meter, for example. The higher an object's density, the higher its mass per volume. The average density of an object equals its total mass divided by its total volume. A denser object (such as iron) will occupy less volume than an equal mass of some less dense substance (such as water).
Greater the distance between the molecules of the substance, lesser is the speed of sound in it.

Speed of sound is directly proportional to density of matter.
