Reply to comment by MostCuriousExplorer in Would the speed of sound in a metal increase if I heated it up? by Altazaar

Sound can travel through any medium except vacuum. Temperature is only enforcing a control because it changes other physical and mechanical properties of a material. Its better to think about those different parameters individually, because the temperature effects are non linear, and vary by material.

Remember- freezing point is simply the point at which a liquid becomes solid (typically we talk about this for water, which occurs at 0 centigrade at standard pressure). We can still transfer pressure waves, the state of matter will change the speed though.

Do you know if there’s any research/reading material available that shows the differences by metal?

Sorry, don’t wanna bog you down with questions lol.

I only really deal with it in rocks. The same physics applies to all metals (and other materials!). There's a huge amount of metallurgy research though - look for stuff on young's modulus, bulk modulus and shear modulus. P wave velocities (sound wave, acoustic wave, compression wave - all mean the same thing) aren't used as much in metal analysis, but they are used. You can use the moduli and density data to work out how P wave will respond though.
