Q:

# Through which substance does sound travel fastest?

A:

### Quick Answer

Sound travels fastest through solids. The density of the substance that sound waves move through, as well as its elastic properties, determine its speed.

Sound is a disturbance through a substance that is perceived by the ear and responded to in the brain, as stated by NASA. A substance transmits sound the vibrations move from one molecule to another, creating a wave. The speed at which sound travels changes according to whether the substance it is moving through is a gas, liquid or solid.

When the molecules are far apart, such as in a gas like air, the sound wave travels more slowly because there is a greater distance between the molecules. If the gas is damp, such as humid air, the speed increases. Sound travels faster in a liquid; in fact, the speed is roughly four times greater in water compared to air because of the density of the molecules.

However, sound achieves its fastest speed in a solid, such as metal, where the molecules are tightly bonded and configured more densely than they are in gas or liquid. This means it takes less time for the sound vibration to move from molecule to molecule, so it travels more easily, and therefore, faster.

Sound travels in waves from a transmitter to a receiver through a medium. The wave is produced by the vibration of particles in mediums such as gases, liquids and solids. Because sound requires a medium of interconnected and interactive particles, it cannot travel in a vacuum such as space.

According to Pyramid Air Gun Mall, muzzle velocity is calculated by multiplying the grain of the bullet or pellet being fired from the gun by the feet per second the bullet travels after being fired. Divide this number by 450,240 to calculate muzzle velocity. The final number is a constant derived by two times the acceleration of gravity by 7,000, which is the number of grains in a pound.
