This scenario will be where @sethoflagos's thermodynamic analysis has a practical application. While posting, I had uranium enrichment by centrifuging UF6 in mind. While I have the opportunity, I need to clarify that I've quoted Gibbs' Free Energy rather too freely in my post. In context I'm referencing more of a total free energy so dH should be understood to include gravitational potential energy which is indeed the the active quantity. It's the -ve change in this that enables a +ve entropy change. Analogous to an exothermic reaction without actually being one! Link to comment Share on other sites More sharing options...
