Question

What would happen to the speed of a sound wave if the temperature of the medium rise?

A.The speed will increase.
B.The speed will decrease.
C.The speed will not change.
D.The speed will initially increase and then return to its earlier value.

Answer 1

A

Answer 2

Thanks thats what I thought

Answer 3

because when temperture rises ,then atoms AND particle present in environment began to move fast,so one particle reaches rapidly to other one, and bcz of this rising sound waves also move fast and result is that speed of sound wave rise.

Answer 4

no mention :)

Answer 5

It depends on the material, because the restoring force in the medium that supports the wave is different. In gases, the restoring "force" is just entropy, so it increases at higher temperature, and the speed of sound goes up with temperature.

But in solids, the restoring force is the chemical bonds between atoms, and these are weakened at higher temperatures -- so the speed of sound goes down with temperature.
