fatoumata Posted February 5, 2009 Share Posted February 5, 2009 Hi guys!! New question: Is atomic spacing constant?, take copper in example. If it's not what is the explanation of those changes in general? Link to comment Share on other sites More sharing options...

DrP Posted February 5, 2009 Share Posted February 5, 2009 I don't know for sure - but here is my guess. Please shoot me if I am wrong. When copper is cooled down - the metal contracts. I don't see how it could contract unless the atoms were getting more closely packed together. As it heats up, the atoms would vibrate more and the distance between them would increase and the overall parameters of the piece of metal expand. I'm sure it's more complex than that - but that would be my 'off the top of my head' guess. Would need to look it up for actual real world scientific answer (not DrP's imaginary world answer).

GDG Posted March 28, 2009 Share Posted March 28, 2009 Hi guys!! New question: Is atomic spacing constant?, take copper in example. If it's not what is the explanation of those changes in general? Nope. Depends on temperature, pressure, crystal structure, etc. Link to comment Share on other sites More sharing options...
