Homework Help: Is this thermo process reversible?

  1. Nov 18, 2009 #1
    1. The problem statement, all variables and given/known data
    If 0.8kg of water at 100 celsius is mixed with 0.8kg of water at 0 celsius, is this process reversible?

    2. Relevant equations
    S = mcln(T_2/T_1)

    3. The attempt at a solution
    I've already calculated the entropy of the process, which is 81.1 J/K. But how do I know if it's reversible?

    How can it be reversible if entropy is generated? Entropy is generated for irreversible processes right? I think I remember this, but correct me if I'm wrong.

    Oh. I seemed to have skipped that part of the lecture. Thank you!
