Heat and vibration

[gonelli]

This may sound like a very strange question to ask, but since heat is a result of atoms/molecules in an object vibrating. Is it possible for something to have such a high temperature that the vibrations of the molecules will be enough to produce an audiable sound that a person could hear a perhaps a humming sound?

no, the vibrations are far to small and the frequencies too high even at very low temperatures.

Yes. It's called thermoacoustics...

 

Here's a wp page on an application of it:

A quick note though, it's due to temperature not heat, heat is an energy transfer.

Figured that might be answer, it makes sense. Thanks insane_alien.

 

Thermoacoustics looks very interesing, may have to do some more reading on that.
