Homework Help: Which quantity is conserved?

  1. Oct 20, 2008 #1
    1. The problem statement, all variables and given/known data
    Which of the following quantities is conserved?
    1) Energy
    2) Heat
    3) Entropy
    4) Force

    3. The attempt at a solution

    I would believe that the energy is conserved. I don't know about Entropy, can some explain that in simple terms for me. Thanks

    Re: Conservation

    Hi logit167,

    What do the laws of thermodynamics say about entropy?
