Does sound travel best through solids liquids or gas?

Answer 1

In general, sound travels fastest through solids, slightly less fast through

liquids, and slower through gases.

This is because the particles (atoms or molecules) in a solid are touching

each other and rather fixed together. That is why a solid is "solid."

In a liquid, the particles are touching each other, but they are not fastened

to each other quite so strongly as they are in a solid. Some of sound's

energy is wasted pushing the particles around because they can slide past

each other. Some of sound's energy is wasted that way and that is why it

moves slower.

In a gas, the molecules are rather far apart. For sound to travel through a

gas, the molecules must move quite a distance before they collide with other

molecules. Sound energy cannot move as quickly when the molecules are not in

contact with each other.

Answer 2

Sound travels faster in solids than liquids or gases.

Answer 3

Liquids
