    here's the problem http://picasaweb.google.com/RBWang1225/Thermodynamics#5412090936157167154 [Broken]

    and this's my ideas http://picasaweb.google.com/RBWang1225/Thermodynamics#5412094345461831986 [Broken]

    Re: entropy

    Welcome to physics forums. Please note, use the standard font and font size when posting here, unless there is good reason not to.

    There is an error in your integral for Q, since
    dQ = P dV, not dV/P
    on the isothermal paths.

    Also, look up the relation between dS and dQ to help with calculating the entropy change.
