Homework Help: Residual Entropy Part II

  1. Aug 22, 2006 #1
    Hi all,

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

    https://www.physicsforums.com/showthread.php?t=129153"

    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?
