Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are farthest apart.
Why are sound waves travel slowest in air?
If a material is very dense the molecules or atoms are very closely packed together and sound can move very fast. In a low density material, like air, sound travels much slower because the atoms are farther apart.
Why does sound travel faster in liquids than gases?
10.2 Speed of sound (ESACZ)
The speed of sound depends on the medium the sound is travelling in. Sound travels faster in solids than in liquids, and faster in liquids than in gases. This is because the density of solids is higher than that of liquids which means that the particles are closer together.
Where do sound travels slowest?
Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids.
What material does sound travel slowest?
gases
The speed of sound depends on the medium in which it is transported. Sound travels fastest through solids, slower through liquids and slowest through gases.
What is the slowest speed of sound?
gases
In colloquial speech, speed of sound refers to the speed of sound waves in air. However, the speed of sound varies from substance to substance: typically, sound travels most slowly in gases, faster in liquids, and fastest in solids.

What characteristic of sound explain why sound travel slower in the air than in water?
Sound is a pressure wave, but this wave behaves slightly differently through air as compared to water. Water is denser than air, so it takes more energy to generate a wave, but once a wave has started, it will travel faster than it would do in air.
Why does sound travel fastest in solid and slowest in air?
Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are farthest apart.
Why does sound travel faster in warm air?
Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly. The speed of sound at room temperature air is 346 meters per second.
Why does sound travel slower in liquids than in solids?
The distances in liquids are shorter than in gases, but longer than in solids. Liquids are more dense than gases, but less dense than solids, so sound travels 2nd fast in liquids.
Do sound waves travel faster through low density gas or high density gas?
Air Density
Just as solid objects allow sound to travel faster than less dense ones, the density of gasses affect how quickly sound travels, as well. For example, sound will travel faster in hydrogen than regular air because it is a much denser gas.
Why does sound travel faster in water than air?
Sound waves travel faster in denser substances because neighboring particles will more easily bump into one another. Take water, for example. There are about 800 times more particles in a bottle of water than there are in the same bottle filled with air. Thus sound waves travel much faster in water than they do in air.
What affects the speed of sound?
The speed varies depending on atmospheric conditions; the most important factor is the temperature. Humidity has little effect on the speed of sound, nor does air pressure by itself. Air pressure has no effect at all in an ideal gas approximation.
Does sound travel faster through air water or metal?
In fact, sound waves travel over 17 times faster through steel than through air. Sound waves travel over four times faster in water than it would in air.
Does sound travel faster in denser materials?
A substance that is more dense per volume has more mass per volume. Usually, larger molecules have more mass. If a material is more dense because its molecules are larger, it will transmit sound slower.Thus, sound will travel at a slower rate in the more dense object if they have the same elastic properties.
Why does sound travel faster in helium than air?
The speed of sound in helium is faster than in air because the helium is lighter than air.Sulfur hexafluoride makes your voice sound very low because sound travels slower in heavy gases.
In which of the following does light travel the slowest?
diamond
The indexes of refraction for diamond, air and glass are, respectively, 2.42, 1.00, and approximately 1.50, depending upon the composition of the glass. Light travels slowest in diamond.
Which metal sound travels fastest?
Steel
Sound travels faster in Steel than any other liquids. In steel, the density and elastic properties are more than other given mediums.
Does sound travel faster or slower as temperature increases?
Therefore, sound travels faster at higher temperatures and slower at lower temperatures. Solids are much more elastic than liquids or gases, and allow sound waves to travel through them very quickly, at about 6000 feet per second.
Why does sound travel faster in saltwater than freshwater?
Sound and Salinity
In seawater, sound travels up to 33 meters per second faster than in freshwater.Sound travels faster in the ocean because there are more molecules — specifically salt molecules — for waves to interact with, as well as higher surface temperatures.
How does sound travel through the air?
Sound is all about vibrations.
The source of a sound vibrates, bumping into nearby air molecules which in turn bump into their neighbours, and so forth. This results in a wave of vibrations travelling through the air to the eardrum, which in turn also vibrates.
