Residual Entropy Part II

  1. Aug 22, 2006 #1
    Hi all,

    first of all i would wish to take reference from this thread.


    Can someone answer this qns....since atoms at absolute zero can still be vibrating, the entropy will be not zero for all molecules in this world at 0 K right?

    Q 1. Pls ans simply, as in give a yes or no ans 1st, then explain, i am quite confused in this topic....:P

    Any help will be appreciated!

    Q2 .another qns, it is said that a perfect crystal will have zero entropy at 0 K, but shouldn't it have some form of vibrational energy in it(Zero-point energy), with a bit of motion, there should be more that one way to arrange the molecules.....so how can it have zero entropy?
