That actually varies, depending on the specific liquid.
it travels fast in gases
Yes sound can travel in liquid, its speed is lesser than that in solid and more than that of gas.
depending on the nature of the solid liquid or gas. usually gas the fastest followed by liquid than solid.
A liquid
Oxygen
A medium. Gas, liquid or solid. It can't travel in a vacuum.
no from what i have learned light travels faster then sound
No, sound cannot travel in a vacuum. Sound moves by vibrating particles of a solid, liquid, or a gas. Since there are no particles in a vacuum, sound cannot travel through it.
Solids
1000 feet
3400mph
I believe you mean "why does it matter how fast sound can travel?" There are many reasons for why it matters to know how fast sound travels. it can help with determining the distance of a lightning storm, tuning instruments, and is helpful with ballistics. -Tychusfindlay919
