    Graduate Where does the unavailable energy come from in Joule expansion?

    Its not joule thomson effect.Its free expansion of ideal gas during which temperature remains same due to perfect thermal isolation

    Graduate Where does the unavailable energy come from in Joule expansion?

    We all know that in free expansion of gases under adiabatic condition and keeping the temperture constant ,we get that no work is done by the gas.Moreover since del(Q)=0, del(U)=0 according to first law of thermodynamics.But we get a increase of entropy by an amount Rln2.Now the question is that...
