Question

Why do sound waves travel at different speeds in each gas? (gases are : air,carbon dioxide, and helium)

Answer 1

@timo86m

Answer 2

i guess it is the density of it.

Answer 3

Sounds like a good guess, @timo86m! What do you think, @QueenBee232

Answer 4

I agree could you be a little more specific though?

Answer 5

well the less space between atoms the less collisions the less sound.

Answer 6

the bulk modulus of the medium effects the propagation speed of pressure waves, this is a ratio of density and fractional change in volume. Moduli is a fancy word for a unit of some kind e.g youngs modulus for a material's 'sterdyness'.

Answer 7

awesome thank you!! :)

Answer 8

I'm not sure who to give the medal to though :P

Answer 9

I guess since timo answered first he should get it

Answer 10

thank u!! :)
