Does the speed of sound change in metal when heated?

[volican]

Is the speed of sound different through the same piece of metal when it is heated compared to when at ambient temperature?

What are your thoughts? What things affect the speed of sound in a material?

 

[volican]

I'm thinking it does because the density would be different.

I would think so too, but I think the speed of sound in a material depends on other things as well. I'd look up the speed of sound in materials (maybe start at Wikipedia), and look at the equation there.
